For Emergency Contraception "I am a teen, and if you are one too, you might want to read this if you're stressing and want to know how this works. I had sex with my boyfriend, he came in me with no condom. We bought Aftera about 1 hour later. My boobs were sore for about two weeks, it first started the day after I had taken the pill. The pain may get really bad, but just breathe and relax, it's a side effect. I got cramps here and there, but it would feel like a little kick to my stomach. Then I had spotting for one day. I thought I was pregnant because of the dark color, but that is also a side effect. Just breathe and let the pill do its work. Plan B and Aftera are the same thing, same ingredients. Don't dig through every website trying to see if you're pregnant or not, it's okay."

For Emergency Contraception "A week ago, I had pull-out sex with a guy friend - desperate times, desperate measures - and he pulled out in time. But I checked my app, and I was in my fertile window, so I freaked out and went to CVS at 2 am, and Aftera was all they had in store. So I took a chance, and I didn't really notice any symptoms besides sore boobs. Then this morning, I woke up and was cramping really bad and had brown spotting. Of course, Google said it was implantation bleeding, so I sped to Walmart to get a pregnancy test. Of course, it was going to come back negative, it's only been a week. But I am super high anxiety, and I did some more research and discovered it was just the pill working. It is 5 am, and I'm sitting here still freaking out, reading through all these for peace of mind, and I started bleeding with clots. As far as I know, I'm not pregnant, so I'll say it worked for me! Girls, stay off the internet."

For Emergency Contraception "It worked. My girlfriend took the pill on July 9th within 18 hrs of unprotected sex after the condom broke. Eight days later, she had a light period for four days. A month later, around the first week of August, she had extremely sore boobs. On August 20, she had another period that was extremely heavy. I sweated about this the whole time and read every review on this site and others. Just wanted to give some hope to the next person who reads this!"

For Emergency Contraception "I took Aftera about 12 hours after unprotected sex on the day I was ovulating. I opted for Aftera because Plan B wasn't available where I was. I have taken Plan B, ella, and other emergency contraceptives before. All very effective with little to no noticeable side effects, other than throwing off your period's schedule. With Aftera, I didn't have any side effects until about 7 days after I took the pill. An extreme amount of bloating, cramps, extremely sore breasts, and a tightening feeling in the stomach, which for me made me feel as if I were pregnant. Being that with both of my pregnancies, the tightening of the stomach was my most noticeable change in my body. I wasn't due for my period until 13 days after I had sex and wasn't initially worried, but with all of the side effects and having unprotected sex when ovulating, it had me feeling as if I was pregnant. Day 11 arrived, and the side effects were so strong, but my period started. NOT pregnant!"

For Emergency Contraception "My boyfriend and I had sex on the very last day of my period. I keep careful track of it and keep note. Without noticing, the condom broke and came in me (Jan 20). It was 6 a.m. and there were no pharmacies open around me, so I had to wait until 10, a good 4 hours after the incident. CVS didn't have Plan B and opted for Aftera, the next available. She said it was the same thing, only $10 less. Two weeks after taking the pill, I had terrible breast tenderness, swelling, I had light cramps that would come and go every so often. Three weeks came and still no period. FINALLY, on Feb 18, my period came. This pill is extremely strong, different side effects for different people. Hope this helps someone. GOOD LUCK, GIRLS!"

For Emergency Contraception "I still don't know if this pill works. I'm late a few days, my breasts feel like they're going to explode, and I get these light to moderate cramping every single day. I didn't feel symptoms right away, it actually started like a week after, and it's been two weeks already. I took Aftera after ovulation, so I hope it doesn't fail me."

For Emergency Contraception "I took this pill after I had unprotected sex. I went in wanting to buy a Plan B, the cashier asked me if I wanted to buy Aftera. It's cheaper, she said, it worked the same. I took the pill, a few hours later, I was having cramps, tender breasts. It felt like a cold. Anyway, the pill worked for me, but I got my period 6 days late. I was panicking the whole time thinking I was pregnant. I took a test, it came out negative. If I were to buy the morning pill again, I would definitely go for Plan B, no matter the price. My period was always on time with it."

For Emergency Contraception "I took Aftera approximately 12 hours after having unprotected sex while I was ovulating. Even though my husband used the 'pull-out' method, I felt that he ejaculated a bit inside. The drugstore only had Aftera available, they ran out of Plan B. The pharmacy told me that it was the same thing as Plan B. This is my first time using the morning-after pill. I was scared to take it after reading some reviews. But everyone's experiences are different. I had some side effects after taking the pill, such as feeling tired, a little dizzy, and I took a nap-that was on the first day. I had slight cramping on and off for about 5-7 days, breasts felt somewhat tender, but all that went away. And I got my period in time, so it wasn't too bad."

I had horrible breast tenderness, cramping, and fatigue. My period did come on its expected date. My period was a bit heavier and a bit longer by two days, but at least I'm not pregnant!"

For Emergency Contraception "I'm 36, 182 pounds, and I was ovulating on the day we had sex, and my partner didn't pull out. So I went to the local pharmacy and took the pill maybe 40 minutes after we had sex the same day. I took a pregnancy test 7 days later, and the test came back negative, twice. About 6 days after I tested for pregnancy, my cycle came 2 days earlier than scheduled. I was scared and worried, had sore breasts, and had a lot of hunger pains. I know it's easier said than done, but just be patient and know it'll be okay, and it works."

For Emergency Contraception "On 9/30, the last day of my period, my husband and I had unprotected sex. Plan B wasn’t available at CVS, so I took this pill 30 hours later on 10/01. A week later, 10/08 (aka my “expected ovulation date”), I experienced the worst tightness in my stomach as well as cramping/spotting, breast tenderness, and severe migraines/light sensitivity. The week of 10/16, the spotting was gone, but my PMS was out of control, hormonal cystic acne took over my face (terrible like my teen years, I am 31 now), and my breast tenderness came back with a vengeance. My period was due around 10/26, but I decided to take my first pregnancy test on 10/23, which was negative. I took 2 more on 10/25 and 10/30, which again were negative. Still no full period as of Nov 2nd. Since all my pregnancy tests came back negative, I’m assuming it worked, and my period will start eventually or next month. Overall, it’s not worth taking, especially with the symptoms/period delay."

For Emergency Contraception "I do NOT recommend this pill!!!! I’ve taken Plan B before, and it did not have the same side effects at all. Plan B is more expensive, but definitely worth it. I took this pill about 48 hours after sex, and everything was fine at first. I then started my cycle about 15 days earlier than usual, which I assumed was normal because I think it says it can either make your period early or late. Anyway, my period has lasted about 9 days now (and counting!!). This seems insane to me, considering my periods usually don’t even last the full 5 days. I have also had breast tenderness since I even took the pill and got really bad cramps during the first few days of my period. In the end, I guess it got the job done because I’m not pregnant. However, I will never take this pill again. I strongly suggest taking the Plan B over this one if you can!!!! I only took Aftera because my pharmacy didn’t have Plan B."

For Emergency Contraception "Okay, so I had a slip-up June 27, 2 days after my cycle had just ended (broken condom). The following day, I headed to my local CVS to get Aftera. I took the pill, no worries. My boobs were sore for two days, as always when I expect my period. It went away, then July 11 came, and I was spotting (6 days after ovulation). I thought it was my period, but it was just spotting. It didn't even fill a pad, but it was red, fresh blood, so I wasn't sure to call it implantation. Anyway, I spotted for the following 11 days with light cramping. My period was due July 18, the spotting continued. Today, July 22, I have begun to bleed enough to need a pad, which had me feeling super excited and blessed. I believe maybe my stress level had a lot to do with the spotting and late bleeding. I used to get my periods late in the month, so maybe it's just changing back to that. I think it was some kind of hormonal imbalance, but I vouch for Aftera because I'm not pregnant (I took Aftera 15 hours after sex)."

For Emergency Contraception "I had sex with my boyfriend on the 5th of April 2019, which was like at 11 pm ish. We used a condom, but when he pulled out, the condom was still inside of me, so he had to pull it out. I was scared that I had cum in me, so I went and got Plan B the next day and took it about 5:00 ish, which was 18 hours later. When I took it, I didn’t experience anything, but when I woke up the next morning, my boobs were so sore. But this kind of sore boobs I never experienced before, but that was about all the symptoms I had. On Tuesday and Wednesday, I felt like throwing up, but I never did throw up, and I felt a little weak, so I thought I was pregnant. Anyway, my period came on that same Saturday like it was supposed to, and I didn’t mess my cycle up, so I’m not pregnant, and it worked! So yes, Aftera worked for me. Just be prayerful and have faith."

For Emergency Contraception "I took this pill on Feb 4th after unprotected sex with my fiancé. Like 2 days after, I started to bleed a little, it did not seem like my regular menstruation. Today is my day 50 of my cycle, my cycle usually lasts around 25 days. Last time I got my period was on Feb 1st. I've had cramps, nausea, and breast tenderness. I did a blood pregnancy test yesterday, and it was negative. However, I haven't gotten my period yet. A lot of side effects. I took Plan B in the past and got my period even before the date, CVS ran out of them. I just want my period to get back to normal and am not planning on taking any emergency pill in the future. It worked in the end because I'm not pregnant, but my cycle is messed up."

For Emergency Contraception "So no Plan B at CVS, and took Aftera. A drunk boyfriend + ovulation window is a recipe for disaster. So he came inside of me & didn’t even realize. Took Aftera within 24 hours. Nothing happened for a few days, then boom, insane back pain, cramps, my nipples still hurt 3 weeks later. I had some spotting for like 3 days a week later (which may have been my period idk??). But still haven’t gotten an actual period, & pregnancy tests were all negative, so not really sure what happened there LOL. Getting an IUD in 2 weeks because oh boy I’m not doing that again."

For Emergency Contraception "I was going nuts! For over two weeks after I had unexpected sex with a friend. I know all bad, but we were drunk. Anyways, I got Aftera 3 hours later, and I experienced the worst: nauseous. My boobs were super sore. I had headaches and cramps for over 10 days! It was the first day of my fertile days, so I was going nuts since I read online it was not effective! I was so scared and worried for a week, googling stuff and whatnot. Lol, close to taking a pregnancy test, but in my case, it did! I got my period a week before the expected date. I was so happy, yet my period was kind of heavy with spotting after days. I promised myself to never do this again. It does work, ladies! But don't risk it next time! Stay positive and try to take it as soon as possible! For me, it worked even on my fertile days, but you never know!"

For Emergency Contraception "Had one of those 'oh no moments.' I was about 2-3 days away from ovulating when it happened. Took the pill the next morning, only experienced sore breasts and bloating. Started seeing pink discharge day 27 of my cycle (I'm normally about 28 days, but it'll sometimes be a few days late), and that made me worry because last time I had pink discharge, I ended up pregnant. I waited about a day, wasn't bleeding much, discharged turned dark brown, still worried. The next day, my period actually started. Way to scare me, period!"

He did not finish inside, and he said he didn’t precum, but I was still nervous - so hopefully this works. I took this pill 1 day later at Sunday 8 pm, and I have experienced cramping and breast sensitivity. But I still have not gotten my period, and it’s Tuesday night. I am hoping it comes... I know it can delay your period by up to a week."

I was expecting my period at the beginning of December, and my period turned out to be 3 weeks late. I was convinced I was pregnant. Had all the symptoms. I could smell everything from a mile away, boobs were sore, cramps, everything made me cry, and nausea. Be patient and try not to stress. The pill will delay your period and your ovulation cycle."

For Emergency Contraception "I promised myself that if it worked, I would come back and write a review since these reviews kept me sane while waiting. Thankfully, it did, and I'm not pregnant. I had unprotected sex the day after my ovulation day. I freaked out and bought an Aftera about 5 hours later and took it immediately. The side effects can best be described as intense pre-menstrual symptoms. My breasts were swollen and extremely sore for 2 weeks until my period. I had nausea, fatigue, but not much discharge. My period came right when it was supposed to, and was paired with heavy bleeding for five days. I'm writing this to reassure many other women going through this. The side effects are similar to pregnancy symptoms, but that only means it's working. The side effects can be annoying and inconvenient, but in the end, the pill works, and I'm sure many prefer this over a child. I hope all women reading this not only feel better knowing others have gone through what you are, but also that your period comes!!"

For Emergency Contraception "This pill made me end up in urgent care. I took it on a Monday and was fine the next day, and on Wednesday, I woke up with horrible stomach pain. It lasted for 6 hours, and I finally decided to go to urgent care to see what it was. According to my gynecologist, I was feeling myself ovulating... I have never experienced any kind of pain like that. I’ve taken Plan B before and never had any symptoms like that. The pain went away about 10 hours after taking some Advil, however, the next day, I was still experiencing tightness in my stomach and cramps here and there. As of right now, I’m experiencing breast tenderness, PMS in general. I’m due for my period soon, so we will see if it makes it late, like everyone says it does."
