For Emergency Contraception "I spent a lot of time Googling about this and never found anything that put my mind at ease, so I wanna share my experiences! I'm 21 years old, and I had sex with my ex, and being the paranoid person that I am, freaked out and took Plan B 38 hours after. I got everything from nausea, breast tenderness, and headaches, it was awful! At first! I got brownish discharge a week after taking it. Then, 3 weeks later, which is today, Jan 30th, I got my period after being 2 days late. Point is, don't worry! Plan B works very well, but it will put your body through a huge mind distortion to the point where you'll think you're pregnant, but you're not! It's insane. I lost much sleep over it and stressed myself out over nothing. I hope this helps."

For Emergency Contraception "Reading a majority of these comments made me feel a lot better, so I promised myself I’d come back and share my experience too. My boyfriend and I had an accident two weeks ago where we found out that the condom broke after he had fully come inside me. I’m not on any birth control, and I’m 23 and fertile. We panicked, and roughly 20 minutes later, I took Plan B. The next day, I felt super sick and nauseous, and the days following, I also started cramping. I was so worried I was pregnant because my period wouldn’t come, and my periods are irregular, so I wasn’t sure when/if it would come. Also, I’ll note that I have painful ovulation cramps, so I was very scared that I was already ovulating, which could render the Plan B ineffective (read the fine print, kids). Finally, on the 5th day after taking Plan B, my period came. I’ve been bleeding pretty heavily for the past 4 days, but I’ll take it over being pregnant any day! God is so good, and I definitely learned my lesson!"

For Emergency Contraception "I had sex on the 18th of January, and the condom slipped. I took this pill to be safe and did nothing but stress myself out waiting for my period and experienced some stomach aches, slight cramping, and nausea. So happy to say that I got my period yesterday, around the time I should have gotten it! Reading these positive reviews really helped calm my nerves."

For Emergency Contraception "Had unprotected sex right in the middle of my cycle. Took this roughly 24 hours after having sex. I felt pretty emotional for a few days afterward. Not sure if that was from the pill or the situation I put myself in. Anyway, for about a week and a half, I felt nauseous, had cramps, was very tired, and had headaches. I also started spotting about 2 weeks after taking it. I thought I was starting my period. However, my actual period was delayed a couple of days. Very happy this product exists! I will not put myself in the situation to have to use it again, however."

For Emergency Contraception "I have taken Plan B a few times over the years. Most recently, I had unprotected sex while ovulating and took the Plan B 2 hours after. I'm not sure why there is information saying it doesn't work if you've already ovulated. A nurse told me it will either delay ovulation or stop fertilization/implantation, which can take days after to occur. Anyway, my symptoms were horrible for over two weeks, I bled for almost a week, which started a few days after, nausea, frequent urination, sore breasts, back pain, moody, etc. But my period came right on time. This was my first time taking One-Step (I have always taken two pills), and I think it just hit my body harder. There is a slim chance of it not working, so please relax and remember these symptoms are normal."

For Emergency Contraception "(Took during ovulation) I got every symptom possible. Sore boobs, nausea, cramps, spotting, dizziness, headache. Symptoms lasted almost two weeks. Thought I was for sure pregnant. Period ended up coming a few days earlier than expected."

For Emergency Contraception "I took this after having unprotected sex on the day I was predicted to ovulate. I felt mildly nauseous the first day I took it and very fatigued for the following 3-4 days. After a week, I experienced bad cramping and had a heavy flow for about 5 days. I’m not sure if this was my period because it would have been about 2 weeks early, now I’m during the point in my cycle where I normally would have gotten my period, and I haven’t. I took a pregnancy test, and it was negative, so the Plan B was effective. It is just a mild annoyance that now my cycle is irregular, but beats having an unplanned pregnancy. The anxiety of taking the Plan B was worse than the actual side effects, so don’t let the horror stories scare you! Most of the side effects are nothing that you don’t deal with during a regular period, and trust that the pill will do its job."

For Emergency Contraception "I took this 16 hours after sex with a condom. I was paranoid, and alcohol was involved, so I couldn’t exactly remember what happened. I was 4 days before ovulation. I had a few side effects like some back pain and slight nausea. I spotted exactly a week after I took the pill for a couple of days. I got my period two days early after the longest and most stressful two weeks of my life. It was lighter than usual but lasted its normal length. I am so grateful for this pill. Stop googling things and let it run its course."

For Emergency Contraception "Plan B served its purpose and worked for me when I had sex with no protection during my fertile window. However, the lack of information regarding the side effects is really concerning. In many credible websites, it is stated that the side effects last at maximum one week. Well, that certainly wasn't the case for me, and as I can assume by reading the reviews here, not the case for many people. After the first few days of taking the pill, I experienced no side effects. Only after 4/5 days of taking it, I started experiencing spotting, similar to my regular period, but that only lasted for about 3 days. After that, I experienced severe headaches, nausea, and really drastic mood swings for the rest of the month. It's an incredible high dosage of hormones, and it can mess up with your body and make you go through a pretty tough time for way longer than one week. I got my period exactly one week late from when I expected, so I can't really complain in that regard because it does work."

For Emergency Contraception "I promised I would come back and write a review after I knew it worked since everyone else’s reviews helped me not lose my mind. I had completely unprotected sex after a few too many drinks on March 20th. Little did I know that it was the day I was ovulating. I went and got the Plan B about 12 hours after the deed. I was terrified because I read that it doesn’t work if you are already ovulating, but I figured it wouldn’t hurt to try. I also read that it doesn’t work if you are over 155 lbs, and I am almost 200 lbs. The first day, I just had a little bit of an upset stomach but nothing major. Five days later, I started having cramping, nausea, and sore breasts. I thought for sure I was pregnant because I had all of the same symptoms with my pregnancy with my son. Needless to say, I was freaking out! Well, fast forward to the 31st of March, I started spotting, which I thought for sure was implantation bleeding, but today is the 1st of April, and I have my actual period. It works, ladies!"

For Emergency Contraception "I’m writing this review in hopes that it eases my still-overthinking brain. I took Plan B twelve hours after having unprotected sex, three days after the end of my period. No nausea, no vomiting, nothing. Feeling fine. A week later, I started bleeding dark red blood, which lasted for about three days before it became this dark, brown, clumpy discharge. Discharge lasted for nearly eight days before the dark red blood returned. During these two weeks, I’ve had the worst flu and had severe hot flashes. I felt absolutely miserable and completely out of whack. The second bleeding was about three days before my expected period, so I’ve assumed it was such. However, it was a lot lighter than normal. The pill works but can really mess up your system."

For Emergency Contraception "I took this pill April 25th, and now a month later I’ve been dealing with nausea, hot flashes. I don’t feel like myself. I haven’t started my period, and I took 3 tests, all coming out negative. I just want to feel better. I’ve been feeling like this for like 9 days now, and I just want to go to the doctor and see what I can do to get rid of this sick feeling. Worst pill ever! I’ve taken this pill before, and it’s never made me feel this way."

For Emergency Contraception "After my odd experience with this pill, I knew I had to write a review to comfort anyone that was as anxiety-ridden as I was. I took Plan B the first day of my period (I had unprotected sex with my bf the day before). I experienced no symptoms for about 2 weeks after taking the pill. But the next 2 weeks were some of the most excruciating days of my life. I experienced headaches, nausea, and insomnia at record highs. I was beyond nervous that I was pregnant, even though my ovulation timeline didn’t line up. I was supposed to get my period on January 1, 2020. Instead, I got it just one day later. So for anyone reading this, relax. Stress and anxiety fill your head with doubt and can make symptoms more daunting than they really are. This pill worked for me, but I had to give it less than a 10 review because of my symptoms. Going forward, stay protected and have a little faith."

For Emergency Contraception "I took Plan B 10 hours after having unprotected sex with my boyfriend, and for two days I was nauseous, and I had no appetite, but that passed. A week later, I got my period, but it was extremely heavy with blood clots, but I'd rather have a heavy flow than a baby."

For Emergency Contraception "So I promised myself if this works, I have to write a review to put someone out of their worrying misery, because believe me, I was scared for 2 weeks straight. So I had sex with my s/o on August 1st, with no condom or form of birth control (yes, I know, dumb, but hey, I'm human, ya know) and he came in me, completely. On this day, my period tracker app said I was fertile, so this was completely worst-case scenario to me. I took the Plan B 3 hours after the incident, but boy, let me tell you! I was nauseous for the whole week! In my head, I was like, 'yup, I'm done for. I'm pregnant.' Fast forward to August 17th, I got my period a day early and it is heavy and painful. Plan B works. Relax, please!"

For Emergency Contraception "Just want to say this pill WORKS! But you really have to take it ASAP! I took mine about 30 hours after having sex using withdrawal, and I got my period right on time. Take some Gravol and/or Tylenol with it to avoid nausea/headache, and remember that although the side effects of the pill are almost exactly the same as pregnancy, you wouldn't be feeling them until at LEAST 2 weeks after sex. DON'T STRESS, and try to keep your mind off worrying because that'll delay your period, and ESPECIALLY don't do research on Google because that will just freak you out even more (trust me, I freaked out so much I fainted). I would recommend having this pill in your medicine cabinet in case of an emergency so you have easy and quick access to it. xo"

For Emergency Contraception "I had unprotected sex, according to my period tracker app, a day before ovulation. I took the pill within 3 hours (after MUCH anxiety because it seems like a big dose of hormones. I am a pharmacist, lol), and I didn't feel anything alarming in terms of side effects (nausea, vomiting, etc.), BUT I did feel INSANELY tired. I pretty much slept the entire day. However, things got rocky a week after I took Plan B. I noticed that I was lightly spotting and freaked out because I thought it was implantation bleeding. I literally worried myself sick and bled/spotted for a week until today, and my actual period started up. It came on time, a day early if I had to be accurate. I just wanted to let everyone know that this pill is effective when taken within the time frame (sooner the better, of course), and there is no point in researching symptoms of pregnancy or whatever because it will only make you worry and stress out more. Best of luck, ladies!"

For Emergency Contraception "I had sex during my most fertile time! The condom broke, and I was freaked out! I took Plan B 30-36 hours after it happened. I was super tired the day I took it and slept most of the day. I then received bad cramps, I thought I was 'implanting'! A few days later, I started getting nauseous and back pains, I thought I was pregnant! That continued for almost a week. And I got really sick. My boobs hurt, and I had awful pain in my back. At that point, I was terrified! Now, 2 days late, I received my period!"

For Emergency Contraception "Basically, it works. I promised myself if I got my period I would write a review! I took the pill on the 11th day of a 30-day cycle (a day before the fertile window, a week or less before ovulation). An hour after I took the pill, I instantly felt nauseous, and then the headaches kicked in. A little while after, I had diarrhea (but that occurred only once for me). The following week, I started experiencing HUGE MIGRAINES, and then I felt REALLY DEPRESSED (I cried and felt really pessimistic about everything). These migraines went on for a little over a week for me. In the third week, I felt fine; my migraines became minor headaches, and then I started spotting little by little. (I also took 2 preg tests; they came out negative.) My period spotting was heavier than the pictures seen for implantation, and it's the 17th day since I took the pill. Today is the 29th of July, and I finally got my period. :)))) Don't worry about a thing."

I also got a white cloudy discharge. So just by all these symptoms, I just knew (well, I was really sure) I was pregnant. I took 5 tests, all negative. I even scheduled an abortion appointment, smh. Today, 6/26, I got my period. The pill works!"

When I tell you this messed me up, it did. For the whole month, I felt dizzy, nausea, cramps. I thought I was pregnant for sure, so I took 5 tests, thankful all negative. I was about to go take a blood test since my period was late 2 weeks, but today, the 16th, I finally got my period. Did the pill work? Yes, but it messed up my period and hormones."

For Emergency Contraception "(The first review I wrote was too long, so I can’t go over my entire experience and all of the tips, but I’ll try my best). The pregnancy test came back negative, my bf and I still think we are too young to have kids. I’ve been bleeding for over ten days and somehow still alive. Though I perfectly expected to start my period late due to the pill and the anxiety on the first and second days, it started early. So, trust the pill, talk to your supports (like friends that you trust with very personal information), and pay attention to the smallest signs that separate pill side effects from pregnancy. Here are some that I know: - Implantation bleeding is after 10-14 days. - Nausea closely after taking the pill does not mean you’re pregnant, it’d take a few weeks to months before that happens. (I also recommend not believing everything you read for the negative reviews."

For Emergency Contraception "I told myself I would write a review if all went well, and it did. First things first, I've never been on any type of birth control, and my partner and I rarely use condoms because they are painful and often give me chronic UTIs for some unknown reason. Had unprotected sex directly smack in my fertile window at its peak and took Plan B 6 hours later. He 100% did inside, so for people not even sure if this has happened and trying to just be safe, relax. I just got my period today, just about on time, maybe a few days later than usual. No real side effects to report, no nausea or dizziness, everyone's different. I rated this a 10, although $50 out of your pocket, it is well worth the money. $50 compared to the cost of raising a child!"

I did feel a little nauseous after, but I am not sure if that was the med or my stress. I also felt some slight cramps, but nothing much. I am happy to report that I did get my period. My period was right on track with my normal schedule. Doesn't seem to be heavier than normal."
