"I swore that I would come back to this website the day I got my period because it kept me sane. I had sex on my ovulation day and took plan B 24 hours after. I am not on birth control too. He thought he pulled out but being that we had sex a few times we weren’t really sure. I was PETRIFIED. I cried for 2 weeks. On day 10 after taking it I started spotting just like what implantation bleeding looks like. I talked to every person under the sun looking for answers and advice, but I still had to wait it out for the period. The spotting happened for 4 days straight, where it then turned into a period. I was scared to death. I took 3 pregnancy test, all negative and still didn’t believe it. Stay off doing internet searchers, PMS, plan b side effects, and pregnancy side effects are all the same.Stay off your computer and phone don't do all the internet searching and don’t spend $45 extra dollars on pregnancy test. Take one the day of your missed period. Plan b is expensive for a reason, it works EVEN WHEN OVULATING! STAY OFF GOOGLE!!!!!! You got this!!"

"GILRS DON’T STRESS OUT PLAN B WORKS! You might be worried and all but let the pill do the work I’ve taken Plan B 3 times and it was effective and yes u do have side affects and some girls bleed after 5 or 6 days after taking it and it only be for 3 days it’s like a mini period. Also means it worked and yes the Plan B makes your period up to 2 weeks late, it don’t matter if your ovulating it still works, you just have to take it on time so don’t worry u do be getting symptom just like pregnancy but in reality your not so don’t stress out if you have taken one good luck ❤️."

"I promise I’d come back on this to write my experience. On May 20, I had unprotected sex, but there was only pre cum involved. So I bought plan B, approximately 40 mins after and I was ovulating during that time. About 5-7 days after I took the plan B, I spotted for about 4 days. Weeks after I was convinced that I was pregnant by all the symptoms I had. I remember taking 2 pregnancy tests about a week before my period was supposed to come ( don’t do that) it was literally a waste of money. Then I took a pregnancy test after a week of my period being late and it came out negative. I know I took about 6 pregnancy tests all came back negative. Overall, my period was 38 DAYS LATE literally almost 2 months late. Thank goodness, I got my period today July 19 after having my last period on May 13. I pray for all of you ladies who are currently going through the scary situation I went through to stay strong and have faith that your period will come. I truly hope this helps someone."

"This has been the roughest 2 weeks of my life, but I promised whenever my period came I would write on here. Feb 21st the day after my ovulation day but still in my fertile window my BF fully came in me after the condom broke. He bought the Plan B 45 minutes later and I immediately took it. I’m not even close to the age that I want to have kids so I was scared for my life. I did and internet search on EVERYTHING. Reading these reviews helped me but did not stop me from stressing. I experience a little bit of nausea after taking it but I think that was just me overthinking. I also had all my PMS symptoms like sore boobs, back fatigue, and mild cramps. Then just yesterday I had spotting similar to implantation bleeding. (internet said so.) and I was freaking out but today the flow is heavier and it’ll probably get heavier as the week goes. I just wanted to say don’t stress, don’t put a stop to your daily life. And PRAY! even if you're not religious just believe in something :) hope this helps someone."

"I was very dumb and was not using condoms or BC. On my day of ovulation I was convinced he didn't pull out efficiently. The next morning I took plan B. The initial effects were not bad at all. My stomach felt a little off but barely noticeable. 5 days later I started spotting brown which then was red for a about 6 days. I knew this was not my period and apparently this is common. My stomach was bloated all month and I had really weird cramping all month. This pill creates similar side effects to as if you were pregnant so really try not to think about it because it's going to freak you out. After 2 weeks of not getting my period I got a negative pregnancy test but my period still wasn't there. My period ended up coming 21 DAYS LATE. My best advise is to trust this pill and try not to google anything. Your mind will really get the best of you and convince you your pregnant."

"I know there are women on here that are stressing and I'm here to lighten up your anxiety. I had sex TWO DAYS BEFORE my suspected ovulation day. He never finished in me, he just wiped off the sperm and we went again in the same hour. I’ve done some research and it says that plan b is les than 50% effective 1-2 days before ovulation, and I WAS PANICKING. I literally took the pill less than a hour after we did the deed. Best time is to take the pill less than 24 hours AFTER SEX. It will be 95% effective and success drops a lot after the first day. My side effects for the were stomach cramps, insomnia, nausea, fatigue, and backaches. The pill made my period come 11 DAYS EARLIER. Yes, thats good news, but your period will be HARDER AND HEAVIER. But it is better than an unplanned pregnancy trust me. Sis, STRESS WILL NOT HELP. Do NOT look up your symptoms because the first thing that will come up is pregnancy. This is a lesson learned big time. YOU WILL BE OKAY , I PROMISE."

"My partner and I had sex the exact day I was ovulating that was January 24,2021. We used a condom but he didn’t realize that it broke and he ejaculated inside me. I started crying because I’ve never been in that situation before but the next day maybe around 12 hours after we had sex that was January 25, he bought the morning after pill for me and I took it and I bled for 1 day. I swore it was implantation bleeding but thanks to the pill and yesterday on February 8 I got my period so trust the pill ladies. I read all the experiences shared and I want to thank all of you beautiful ladies. I waited on my period stayed off google like you all said and thanks be to God and the pill I got my period yesterday so the pill really works whether you are ovulating or not. So to anyone going through the same thing just take the pill, pray to God, stay off google and read our experiences... Take care lovely ladies stay safe you are loved❤❤"

"Who knew waiting for your period could cause so much anxiety?! I wanted to come and share my update because like many of you these post kept me reassured. I had unprotected sex May 2nd the day before my ovulation day, took Plan B 24 hours later. My period was expected to come May 19th. The 19th comes and no period; I start to panic but understood the pill can cause disturbances to your cycle. One week goes by still no period, so I decide to take a pregnancy test which turns out to be negative. My period is now 16 days late still nothing, at this point I’m convinced I had a false negative reading and decided to take a blood test just to be 100% sure, results come back negative. At this point it’s just a waiting game full of anxiety. My period finally came today! 25 days late!!! (I skipped a whole month) Ladies don’t panic, every ”BODY” is literally different this pill can greatly mess up your cycle but it does work! Lesson was learned, the stress is not worth it."

"Okay so like other people, I promised I’d write a review if this worked. I’m 19 I’ve taken plan b about 6 times total, has worked every time . I had unprotected sex multiple times on the night of the 13th of August, and was fertile and supposed to ovulate on the 14th. I took plan b on 14th around 1 pm. For the rest of August I was insanely moody, bloated, crampy, fatigued, frequent urination, acne prone, and EXTREMELY NAUSEOUS. So basically every pregnancy symptom. I was expected to get my period on the 31st of August, it didn’t come till today, September 11th so almost 12 days late. I had freaked myself out and made myself so anxious thinking I was pregnant that I delayed my period even more. I also spent $60 on taking pregnancy tests. I know it’s so hard not to stress, but the more you do the later you make it, also plan b can make it late on its own. STAY STRONG GIRLS. Everything will work out fine. Reading these reviews really helped me. Just breathe. Good luck!"

"hey girlies! plan b does work during ovulation I’ve taken it a few times when I’ve been at the peak of ovulating . whoever says it doesn’t work do not listen to them. In the past I’ve never really had any symptoms but the last time I took Plan B it was horrible. Plan B made me anxious, sore boobs , STRESS & it literally made me feel pregnant. The more you stress the longer your period will take to stop by and say hello to you. My period was two weeks late , I had horrible hormonal imbalance, for almost a month. girlies please use protection the stress is not worth it!"

"First take a breath and relax you are OK. I had sex on June 25 the day after my ovulation day ( Flo app) and the condom broke and he came in me. I’m young and still live with my parents so pregnancy was a no. So he got me a Plan B which I took a hour later. However, I decided to google the success rate and it says it didn’t work if your ovulating so I literally almost cried, my OBGYN said that it still works, everyone around me kept saying you should be fine so I decide to stop worrying but I still looked on this page everyday for about two weeks and the stories help a lot. I did take a pregnancy test my doctor gave me a few days before my period started and it was negative. Symptoms were nausea a hour after the pill after and then mild cramps which were on and off; closer to my cycle I got sore nipples and cramping. It is now July 10 and I got my period a day late. Have faith ladies the pill works it’s true what they say don’t stress or stop your life for this."

"I promised that I’d write a review if it worked so here I am. GIRLS PLEASE DON'T STRESS OUT!!! I was on the same boat as you all, I was stressing out for so long and tried searching everything up and all that came back to me was pregnancy. I took 4 pregnancy tests & a blood test and it all came back negative and I got my period 12 days late!! The whole month after I took Plan B I was so moody, cramping almost all month. I was crying everyday for no reason, bloating I felt gassy and frequent urination but just because PMS and Pregnancy symptoms feel exactly the same DOES NOT MEAN YOUR PREGNANT. Please don’t search anything up on the internet because you’re going to get more anxious thinking you’re pregnant and trust me it’s not worth it. The pills works beautiful girls, as long as you took it within 1-48 hours of having sex you are okay ❤️❤️❤️ stay safe and stay off the internet xxxx"

"I took Plan B on February 9 an hour or two after the deed was done no protection and he came inside. I was scheduled to ovulate on February 15. I spotted exactly 1 week later lasted around 2 days and it was a dark brown color. I felt completely normal 2 weeks after I took Plan B. After that I started to feel extremely emotional and anxious. My scheduled period day (March 2nd) came by and she didn’t show up I have NEVER been late. Pregnancy tests were negative thankfully. 11 days late I started feeling some pre period cramps I was hopeful these came and went for 5 days. It took a total of 16 DAYS for my girl to finally come through. The pill did it’s purpose I would take it again but believe me I learned my lesson I don’t care how unsexy a condom is I'm going to protect my girl and myself as we all should! So don’t worry sisters!! Be patient and STAY OFF THE INTERNET! I would come here to ease my anxiety and that’s why I’m here to share my experience. Sending lots of love"

"I'm going to start off my saying I’m young enough to be still living at home and getting my mama to buy me food and clothes. So I had sex on ovulation day me being young I didn’t know it’s easy to get pregnant on that day so I was sacred and took the plan b about 26-28 hours later. I did research on a Plan B and it said it’s best to take it in the 24 hour range and it’s not effective on ovulation day so I freaked out didn’t know how I would tell my mama if I became pregnant. Anyway I found this website and saw all the amazing reviews I read at least the same reviews 4 times a day. I didn’t get symptoms days later like everyone else, a week later I had cramps, lower back pain , constipation, bloated and I got no bleeding in between but it all happen at once I look on the internet and saw PREGNANCY. I decided to wait and relax my mind and my period came a day early. I prayed but these cramps are ironic but that’s better than being pregnant but ladies IT WORKS EVEN DURING OVULATION"

"I had unprotected sex 2 days before ovulation, had a bit of nausea and cramping after taking the pill a couple hours after sex. I got my period as normal. Please try to stay as calm as possible and don’t search things up on google because it WILL cause you to stress out and stress affects your period even more. If you convince yourself that you are pregnant, your body will mimic your thoughts, you will be in a downward physiological cycle which will ruin you (speaking from experience, it was the worst 2 months). Please trust the pill. You are loved, you are supported, you are going to be okay. Sending you endless love and support ❤️"

"Sharing this because I couldn’t find any similar experiences online and hope this can help someone! I took Plan B about a week before my period was scheduled to come. *Note: I did not know Plan B is likely to be much less effective after ovulation - its primary function is to delay ovulation.* My first period came right on time, and I thought I was in the clear. Boy was I in for a ride. My cycle is usually around 25-26 days, and my cycle *after* my first period post-plan B was 44 days. So I took Plan B, had my first period on time, but my second period was almost 3 weeks late. During that time I experienced a whole array of symptoms: ice cold hands and feet, nausea, really horrible headaches, crazy moods and generally being very anxious. I’ve never experienced anything like it. Thankfully not pregnant - just know that Plan B throws your body totally out of whack and it may take a few cycles to return to normal."

"Okay so I know many females might be so scared and paranoid - accidents happen. BUT please trust the Plan B pill!!!! It really works! The last thing you should do is start googling ! That was my biggest mistake. They say it doesn’t work during ovulation but I had sex the DAY I was ovulating. Just trust the pill ladies! So I wanted to put my story out here because it was my first time taking plan b. Me and my bf had unprotected sex and he didn’t pull out immediately we were both scared and we agreed that’d he’d buy the plan b. Again I’m young so I didn’t know what was going to happen. I took the pill within 10 hours and I was nauseas and I had cramps every other day come and go for 2 weeks. It’s a waiting game I felt bloated, I used the restroom frequently and I was stresssingggg. I got my period today (after 2 weeks) and its the worsttttt but hey I’m not pregnant :)"

"Hey Ladies! Had to share my experience since there were a few posts on here that helped, but didn’t quite ease my anxiety because my experience was different. I took Plan B 48 hours after my incident. I was also ovulating. I was freaking out because I didn’t have any of my usual menstrual symptoms and also didn’t have spotting after 7 days, like everyone else who took the pill. I did have very mild cramps, 9 days after taking Plan B and mild nausea. I took 2 tests on the day that I was scheduled to get my cycle and they came back negative. I got my period 2 days later than scheduled. This was a total of 15 days after taking Plan B. I’m in a lot of pain, but I’m thankful that the pill worked! So remain calm ladies! Everyone’s body is different. I didn’t have any symptoms of the pill working, until my period arrived. Hope this helps!"

"I promised myself that if/when I got my period, I’d share my experience. I had sex on April 12th, on the last day of my period. It was unprotected and he didn’t pull out in time. He fully came in me. We went to CVS in the morning and I took plan b one-step probably 10-12 hours after sex. My periods are always weird since I’m on the pill, and I don’t get a period every month. I didn’t get a period/bleeding in May. I took at least 2-3 pregnancy tests that all came back negative, but I googled symptoms of pregnancy and freaked myself out so badly that I was convinced I was pregnant and that my life was over. If you worry like I do, I’m here to tell you you’re okay. It’s now June 4th, and my period is technically early by like a week. I spotted yesterday (pinkish/red). But now it’s a heavy flow, and my cramps have been so bad. However, I’m not pregnant and am happy. DO NOT GOOGLE ANYTHING. If you take this pill within 24 hours, you’re okay. Stay strong ❤️"

"I am leaving a review because two weeks ago I was on here reading reviews just to ease my mind. On December 3rd, went on a second date with a guy, and got a little too drunk. Had sex a couple times and didn't realize the condom broke and he came inside. It was 2am so I went first thing the next morning to get plan B. I took it at 9am, I checked my period tracker, realized we had sex ON THE DAY I WAS OVULATING. I was panicked as my period is regular, I always get my period on the predicted day, the ovulation predictor is spot on. Next I'm on the internet finding sites that say Plan B doesn't work when you are already ovulating. I decided to trust the pill and wait. I experienced EXTREME fatigue, breast tenderness, dizziness, bloating and food cravings, minor cramping. more stressing.etc. Fast forward to Dec 15th, low and behold, Aunt Flo showed up a day early! Trust the process, even a woman who has a very regular cycle was saved by plan B during ovulation. Good luck!"

"I don't understand people who give Plan B a low rating because of the side effects. The purpose of this pill is to prevent pregnancy, not make you feel good! And if it's purpose was successful give it the rating it deserves! People need to understand that this is like dropping a hormonal bomb in your body, yes your cycle will be messed up for a while but anything is better than an unwanted pregnancy. I have taken Plan B three times now. This time I was really nervous because I took it on my ovulation day. One week after taking it I started spotting with light cramping, I was scared that the spotting was implantation bleeding but eventually the bleeding got heavier and turned into my period 8 days later. Plan B has worked every time I have taken it so far. Ladies please be patient and remain calm."

I didn’t have symptoms till about 4 days later my breast started to hurt, cramps, nausea I also had gotten a really big nose bleed so I started freaking out. About another week later I got my period which was very heavy. Just trust the pill and relax you will be ok."

"Okay ladies, I have decided to share my experience with Plan B One Step to hopefully help ease even just a few minds, because I know just how bad this situation sucks and how you are searching high and low for some honest feedback. No matter what I say here, you will still be freaking out for a while and overthinking every little thing you feel within your body. Just try your best to be positive and keep busy. Alright, so here goes the story: On Apr. 9 I had sex with a male partner and the condom broke. We didn't notice until the deed was done. Immediately I thought "omg we are screwed". I had finished my last period on Apr. 4 (I was now dangerously close to ovulation). The next morning (approx 6-7 hrs later) we went to the pharmacy to get emergency contraception. I took the pill immediately WITH FOOD. The food part is very important. The pill can make you nauseous and if you vomit soon after taking it, it obviously will not work. The pill contains very high levels of Levonorgestrel, a synthetic version of the hormone Progestin (aka the pregnancy hormone). When you become pregnant, your body produces high levels of Progestin, which prevents your ovaries from releasing an egg (because you wouldn't want your body to be ovulating while you are already pregnant). So, in a sense, the pill tricks your body into thinking it is pregnant and therefore your ovaries do not release an egg for the sperm that is now inside of you to fertilize. The effectiveness of this all comes down to timing. The pill's job is to temporarily stop ovulation, so if you have already ovulated, the chances of it working are lowered. This doesn't mean you are totally screwed! There isn't much conclusive evidence (that I have been able to find) but it is said that even shortly after ovulation, the pill can help prevent a newly fertilized egg from implanting in the uterine wall. It is important to follow the advice to take the pill within 72hrs of the incident because sperm can live inside of you for approx 5 days and the longer you let it go, the closer you get to ovulating and the better chance those little suckers have of locating your egg! Back to the fact that the pill temporarily stops ovulation. This means that Plan B is NOT an abortion pill! So whether you are worried to take it because you are pro-life or you are thinking it will terminate an established pregnancy, it WILL NOT DO THIS! The pill's job is to take action before the sperm and egg ever meet. Now onto the stuff that will literally exhaust you... The side effects. I'm going to be honest here and tell you that looking up your side effects is going to make you think you are pregnant for sure. Almost every possible side effect of Plan B mimics the signs of pregnancy. You could experience: nausea, abdominal cramping, fatigue, headaches, dizziness, vomiting, and spotting. If you are concerned about any of these side effects contact your doctor. They will be your best source of support through this. I experienced mild abdominal cramping (like period cramps) the next couple of days after taking the pill and "spotting" about a week later. The spotting was what concerned me. When I read that you "may experience some spotting" I thought a light little speck here and there, however for me it was almost exactly like one of my periods. My periods are generally quite light (lucky, I know) and my "spotting" was almost the exact same, just slightly lighter and lasted about 3-4 days. It started out fairly bright red and then by the last day turned to a darker red, almost brownish colour. I later found out that this is quite normal. Throughout the duration of my worrisome experience, I took 3 home pregnancy tests to help ease my mind a bit. I took one 21 days after the incident, another 6 days later, and then one like 4 weeks after that (just because I was feeling particularly worried that day). All 3 read negative. This helped settle my mind somewhat. Also, a little info that may be a bit TMI, but about 2 weeks after taking the pill I got a yeast infection (see, TMI). On top of worrying about everything else, I now had a painful and embarrassing infection to add to my list! I was freaking out because I wasn't sure what it was at first (painful urination, labia painful to the touch). Upon +++ research on my own, I found out that this is another possible side effect of the pill. The increased hormones in the pill can cause your body to produce an excessive amount of natural yeast. The same thing can happen to women during pregnancy due to the same reason. So if this happens to you, it's uncommon but not unheard of. The biggest worry I had throughout this entire experience was when in the world was I going to get my period?! The pill can and probably will mess with your cycle. It definitely did for me! I'm not sure if it had anything to do with my size, but I'm thinking that it might have. I am fairly petite (115lbs) and the pill is the same dosage for everyone. I ended up missing an entire period! Talk about going out of mind! Everywhere I read said that the pill could delay your period by a week or so, but nowhere could I find anything about it making you skip an entire period! Just as I was mustering up the plan to make a doctor's appointment, my period arrived! Exactly one month late. Again, I can't stress enough to talk to your doctor if something doesn't seem right! I really hope you found some kind of relief in reading this. There is no sure shot way to know Plan B has worked unless you get a blood test from your doctor or are graced with your Aunt Flo so do your absolute best not to worry yourself sick. Remember, stress can have an effect on your cycle as well. I found it most helpful to confide what I was going through in one really good, trustworthy friend who helped bring me back to reality when my worry was spinning me out of control. I hope everything works out for you, and you share your experiences with others going through the same, terrifying experience. Good luck and think positive!"

"So I said if it worked I would leave a review, because I never leave them, but I wanted to share my experience. I am not on birth control and he didn't wear protection. We had sex midnight Saturday, Saturday night, and Sunday morning. I took the Plan B Sunday morning afterwards. I didn't realize I was ovulating that entire weekend because I don't keep track of it!!! It took 10 days for my period to come on. I began to stress about it, which I tried not to do because the stress can mess with your body too. I'm just so happy it's on. No more sex for me until I'm married!"
