For Emergency Contraception "My boyfriend and I had unprotected sex (I know, stupid!) because he forgot a condom on Sunday, March 10th, around 6:30 pm, he came in me. I had ovulated 8 days before on March 2nd and was expecting my period a week from March 10th. We’re both late teens, so we are way too young to have a child. I took Aftera the next day around 4:30 pm (22 hours after sex) and felt fine the rest of the day. I had bad cramping and bloating for the next 3 days. I also experienced fatigue. My period was a day late. BUT IT WORKED!!! Don’t stress, everything's gonna be okay."

For Emergency Contraception "My boyfriend and I always have safe sex, but this time the condom seemed to come off inside me, and we didn't notice until after he finished. I took Aftera about 1 hour after it happened. It really works. My ovulation window was around that time, and I was freaking out. My period comes every 30 days, and I got it on time! (two weeks after taking the pill). I'm on my third day of having my period, and it is lighter than usual, but not to a big degree. The only symptoms I got from the pill were dizziness, nausea, and fatigue. This was my first time taking Aftera, and it was very effective. The sooner you take it, the better it works."

For Emergency Contraception "So I took Aftera because I had unprotected sex on the last day of my period. He didn’t finish inside of me, but I was worried about precum. After taking the pill, I started feeling tightness in my stomach and cramps. About a couple of days later, I also had some spotting a few days later from taking the pill. About three weeks later, I had tiredness, mood swings, headaches, more urination, fatigue, increased hunger... just about the symptoms for pregnancy. Now my period was 9 DAYS LATE! But I got pink discharge, then I started officially bleeding about three days after the discharge. But I got my period, right now I don’t know about its heaviness or anything, but it feels like it’s going to be a little bit more harsh than normal but pretty normal. It works! I'm not sure if it will work if you had unprotected sex while ovulating. I was very stressed and anxious, so I made sure to leave a review for other women experiencing similar situations! Hope this helps! Good luck!!!"

For Emergency Contraception "Listen, this may put some minds at ease, but if there is anything I have learned... it's use condoms and get on the goddamn pill as backup. Anyway, I had to share my experience with 'Aftera,' which I guess is basically the same as Plan B One-Step. I had sex on June 12 with my partner. He pulled out, but I started freaking out when I looked at my period tracker and realized that day was my most fertile day. Within 2 hours, I went to the store... All they had was Aftera, so I bought that. The next 2 weeks, I had pregnancy symptoms: nausea, head/back aches, fatigue, weight gain, cramps, and very tender breasts and nipples. I was nervous it wouldn't work since I am 340 lbs, severely over the weight limit, but I finally got my period 3 days late. Good luck, all."

For Emergency Contraception "In a 'heat of the moment' situation, my boyfriend and I ended up having sex on May 25. He pulled out and wasn't in for long since it was both of our first times, and we're both in high school, but I was still freaking out. I took the morning-after pill less than 12 hours afterward. Then we ended up having a repeat of this situation on May 30. So again, I took the pill. This time it was about 12 hours later though. I waited anxiously, but reading these reviews really helped me. I was sure I was pregnant. My periods are irregular, so I wasn't sure when to expect it. I experienced cramps, moodiness, frequent urination, nausea, and fatigue. Now it's June 6th, and I just got my period. Don't stress, ladies, just let the pill do its job! :)"

For Emergency Contraception "The condom came off inside of me, and he finished inside of me. This happened during my ovulation. Took the pill December 22, and on December 29, one week later, I did start to bleed a light period, which I wasn't due for until January 7-ish. I didn't have another normal period until March 3. I took several pregnancy tests just to confirm, and all were negative. This pill did make me fatigued. This was my first time ever using emergency contraception."

For Emergency Contraception "I mean, it got the job done, but my period was missed all month, and it gave me the biggest pregnancy scare ever! I got bad cramps and no period, and I felt fatigue and nauseous some days. I truly thought I was pregnant. It delayed my period a lot, and I got bad symptoms and a weird odor. Only gave it some stars because I ended up getting my period, so woohoo!"

For Emergency Contraception "I used Aftera 36 hours after having sex and not using a condom. The pill took effect and gave me symptoms five days later. 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 took Aftera about 2 hours after unprotected sex, and it worked. The condom came off inside of me, so my partner and I drove to CVS immediately and got Aftera for $44. I don't like to take meds on an empty stomach, so I took it after we got lunch. This happened, and I knew my period was due 12 days later. I remember 5 days during the week after I took Aftera that I had short, 2-minute long periods of intense back cramps. It felt like someone shoved a pole down my spine, but it only lasted 2 minutes a day during each of the 5 days. As I mentioned, my period was due 12 days later. I actually got it on the 11th day, so early and damn near close to on time! The period was a bit heavier and more symptomatic than usual - I experienced a bad headache that lasted for all of Day 3, and I was very fatigued on Days 2-4. These symptoms weren't too bad. I was worried after reading these reviews, but my friend/potential partner and I are so relieved."

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!!"
