For Emergency Contraception "This is for anyone worrying about your period being delayed after taking the Ella pill. Had UPS about 5 days before my period was due, so I was very sure I was out of my fertile days, but I took the Ella pill the next day anyway just to be safe. Period didn't come when it was due, but I didn't worry much about it. Then, 2 weeks later, still didn't get it, so I took a pregnancy test and it was negative. 1 week after that, still didn't get it, so I took another pregnancy test and it was negative. On the same day, got brown discharge and went crazy thinking it was implantation bleeding, and it lasted for 3 days. As days went by, I started getting cramps, sore breasts, and feeling tired, and I was convinced that it was pregnancy symptoms, but looking back, I was definitely overthinking it. FINALLY, today, 41 days later, I got my period. I just want to say if your pregnancy test is negative and you still haven't gotten your period, don’t worry, it's just the hormones from the pills messing your cycle up."

For Emergency Contraception "I took Ella two weeks ago after failing to use any contraception. It was day 13 of my cycle, so bang in the middle of my most fertile period. I took Ella about 5 hours after the unprotected sex. Didn't experience any side effects, so kinda forgot about it for 2 weeks. Then yesterday, I got really sick, I was vomiting loads, was really tired, and had a headache. This then sent my brain into overdrive, and I read loads of stuff on the internet about how it doesn't work when you're ovulating and loads of really bad reviews. I was convinced I was pregnant. Today I have come on my period right on schedule, and I am so relieved. Honestly, I would avoid the internet and just wait it out. People are more likely to leave a bad review if they're annoyed than leave a good one if it worked perfectly! But here is mine to put people's minds at rest."

For Emergency Contraception "I also felt really relieved after reading what's written here, so here is my recent experience: I took Ellaone in the first two hours after having unprotected sex. It was around one day before ovulation. I'm super regular, and my cycle lasts approximately 31 days. When my period was already five days delayed, I did a pregnancy test. It came out negative, but some days I was feeling really tired and nauseous. However, when my period got delayed by 14 days, I was still super scared and went to the gynecologist (always go to a professional). She did an ultrasound and another pregnancy test, everything was showing I wasn't pregnant. Finally, my period came 25 DAYS LATE. What I want to say is: it works but has side effects. I really think the best option is to go to the gynecologist to not be stressed because stress also delays the period. I hope this is useful information, you're not alone, talk with your friends and your doctor :)"

For Emergency Contraception "I wanted to submit a review once I had my results to maybe help others in a similar situation. I am overweight, over 250, and took the pill on the 5th day after a contraceptive failure. My cycle is longer at anywhere between 31 days to 44 days at times. I have PCOS. I am diabetic and on Metformin, which has helped me ovulate monthly. All of these factors made me doubt the effectiveness of this pill, but I had to try since our condom broke and I didn’t realize until a few days later. Because this was prescription only and not all pharmacies carry this pill, it was special ordered, which is why I took it on the 5th day. I felt fine the day I took it, but the next day the nausea, back pain, and headaches began. My breasts got bigger and tender, and I was extremely tired. These symptoms persisted for 2 weeks. This pill convinces you that you are pregnant and has delayed my period for over a week. I have done multiple urine tests, all negative, and just got back my blood test negative too."

For Emergency Contraception "OK. So for those who are freaking out about pregnancy symptoms or not getting your period with Ella... you're right. I didn't get mine until 2 weeks after my due date, and I was PARANOID. My test results were negative. I was probably getting PMS symptoms but mistook them for pregnancy. I was CONVINCED that I was pregnant. But my period finally came, so please don't overstress and take a test to ease your mind. ALSO, Ella resulted in more white discharge from my vagina (mucous-y), which scared me a lot. But this is normal and a part of the pill's action. I didn't feel nausea, tiredness, or dizziness at all, but it may differ for others. All I know is that it worked, and please don't stress so much unless a pregnancy test is positive! These reviews really helped me calm my mind, so I hope my review can help somebody too. Your period can and will be late."

For Emergency Contraception "I promised myself that I would write my experiences because this page helped me so much, and I want to help others with my comment. So, I had unprotected sex on January 1. I found out that I was in my fertile days. I decided to buy Ella EC, and I used it on January 6, after my ovulation (ovulation was on January 4). I thought it was too late because I had already ovulated. But it worked for me! I got my period 8 days earlier. But before my period, I had scary pregnancy symptoms. I had white discharge, distention, painful and sensitive breasts, and they became bigger by 1 whole cup size. I was nauseous, and I had no energy. I was sure that I was pregnant, but don't be afraid, these are just the side effects. The first time I used this pill, I didn't have any of them. But this was the second time, and it was horrible but effective. My period arrived, but this is heavier than usual. Please take care of yourself, and use this pill just if it is very SOS."

For Emergency Contraception "Just something quick to help anyone that's worrying. I took Ella one, 30 hours after unprotected sex. My period was due 2 weeks later, making this a very fertile time. My period didn't come, had cramps, morning sickness, and tiredness, which made me even more worried. Did so many pregnancy tests, all were negative. Got my period today, 7 days later. So relieved. The symptoms I thought were pregnancy must have been worry and stress. The morning sickness I think was me waking up and taking tests and getting myself into a state. Hope this helps someone."

For Emergency Contraception "This EC is awful for those that suffer with anxiety, which I’m sure everyone does when it comes to unplanned pregnancy! I have taken ella before now, and I can’t remember the symptoms, so I am hoping that this will help some of you in the future if you’re going through the same thing. Right now, I am extremely tired, my breasts are tender, not to the touch, but if you push down onto them slightly, I’m suffering with light cramps, headaches, and so much stress with worrying! This pill makes you believe you are pregnant. 21 days after sex, I took a pregnancy test - negative. This morning, I took a Clearblue pregnancy test, and that also came out negative. I’m pretty sure if I was pregnant, it would show up on a test by now. This pill works, I’ve used it before, but it is enough to worry and stress you out. It does help to see other people’s reviews to see they are also having the same side effects. Ella one works. It just really can mess up your cycle."

For Emergency Contraception "I found this page when I was stressing out, so I wanted to share my experience too. I took this emergency contraceptive pill, Ella, within 13 hours of the accident. According to my period app, it was during my ovulation days. I didn't get any symptoms after taking the pill, I didn't get my period on time. My periods are always on time! When I was 7 days late, I went to buy 2 pregnancy tests to be sure if I was pregnant. As soon as I got home from the pharmacy, I tested negative. 12 days later, I tested again, and I got the same results. I was getting all the symptoms of a pregnant woman: tired, lower back pain, tender breasts, off food, and crazy mood swings! I was so stressed out! Finally, day 14! I got my period! What a relief! This pill works, but it messes your cycle up! I would only recommend using this pill for emergencies! The stress and the symptoms are not worth it! Good luck, guys!"

For Emergency Contraception "I never leave reviews, but reading other people's comments helped me, so thought I'd share my experience with Ellaone. I was prescribed it by my GP after my husband and I had a split condom 2 days after I ovulated. I was in such a panic as I had read that Ellaone only works if you take it before you ovulate! I felt extreme tiredness and exhaustion almost instantly! I had swollen, sensitive breasts just like I did in pregnancy! The week after, I was nauseous and dizzy. One morning, I thought I was going to faint! I did a pregnancy test 2 days before my period was due, which came back negative. Then I tested again the morning my period was due, and again it was negative. That afternoon, I started having mild cramps, and later on, my period came. The pill definitely is effective but has some scary pregnancy-like symptoms!"

For Emergency Contraception "I promised myself that I would write about my experience with this pill when I got my periods. So I had sex and the condom slipped, so I had to take a pill. Before in my life, I took a different kind of emergency pill. But this time in the pharmacy, a girl recommended Ellaone to me, and I bought it. I took the pill the same day when the accident happened. Then, two weeks later, another accident happened, and I decided to take Ellaone again because it was recommended in the instructions. And let me tell you, I will never take this pill. It made me feel like I was 100% pregnant. I felt dizzy, I had pain in my lower back, and one day I woke up from terrible cramping and I thought it was implantation bleeding. I had a lot of white mucus all the time for three weeks. I was depressed, tired, and sleepy all the time. I was sure I was pregnant. This is how this pill makes you feel. Thank God I got my periods after this awful, stressful time, and I was the happiest. Yes, the pill works, but it gives really bad side effects."

For Emergency Contraception "So my experience with Ella wasn't the best, but I'll tell you right now it worked, so if you're thinking about taking it, just do, it's still worth it!! My period ended on a Wednesday, and I had unprotected sex on Saturday, and since I wasn't on any birth control for over a year, I thought I would be better safe than sorry and took Ella on Sunday morning. The 1st week I just felt a little light-headed and tired, 2nd week I started to get some weird stabbing pain on my left side, 3rd week my breasts were painfully sore and doubled in size, and I started to bloat (it looked like I was already 3 months pregnant), and all my lower stomach hurt. I was gassy, and the stabbing pain continued, but by now it was spreading also to the right side. By this time, I was also feeling nauseous from all the anxiety. After two negative pregnancy tests, my period finally arrived a week late!!! So please don't freak out like I did and just be patient, the pill does its job, but it will mess up your body. Good luck!"

For Emergency Contraception "Well, where do I start? I’m coming here to write a review for any of the girls going through the same as me. I had a man ejaculate inside me, and it wasn’t consensual, but I did the smart thing any person would do and took the Ella One pill 1 hour after, which was on the 14th of July. I’m pretty sure I was ovulating since my period was due on the 27th. Let’s just say this was the worst 2 weeks of my life. I came on this website maybe 100 times a day to reassure myself, but it still didn’t calm me down. This pill gave me so much anxiety, I was crying every single day. I felt tired, cold, hot, both every single 5 minutes. Luckily, I had my girlfriend to help me through this. Yes, my girlfriend, but still I was feeling so low and just anxious. Anyway, I got my period today-YES, 1 day late-and I cried of relief. Do not believe the girls who left bad reviews on here. Stay safe, ladies, I promise you, you’re okay. Sending so much love and hugs!!"

For Emergency Contraception "Wanted to share my experience because last days I read every single one of them to search for some peace of mind. First week after I took it, everything was fine. Second week I started to feel nausea, a bit dizzy, tired, migraines... period was 4 days late, needless to mention how scared I was. This website helped me to keep it all together because 4 days before my period actually came (so starting from the day it was supposed to start) I felt weak, couldn't eat much, and cramps. Just like how I felt when I was pregnant with our first child. Glad I took several negative tests. If you are freaking out, just take a test on the day you expect your period. Don’t panic if your period is late. It’s Ella, it works, but it has a great impact on your cycles. Try to avoid taking these pills. But if you are hesitating right now to take it if you had unprotected sex and want to avoid pregnancy: go for it. You’ll live. But be prepared for messy cycles and feeling a bit off this month."

For Emergency Contraception "Had unprotected sex on the 13th of Dec; he ejaculated inside me. My cycle is irregular, but that time it started on the 1st of Dec, which means it was my fertile window when I had sex. No chance to buy MAP without a prescription, so I went to the doctor and also used suppositories to avoid any stomach pain. So I took it ~42 hours after sex. W1: no side effects; W2: sore breasts, very strange nipples, tired, some pelvic pain, so I was almost sure I was pregnant because I've never felt something like this. So, 12 days after sex (4 days before the next period) I took the 1st test - negative. 2nd - 17 days after sex - negative. My period started 3-4 days later (usually can come earlier but not later), and in the beginning, it was unusually light, but now, on day 2, it seems to be okay. Blood test 20 days after sex showed HCG"

For Emergency Contraception "I took ella one after having sex with no protection (stupid mistake). I'm older and should know better. Even going to the pharmacy to get it is degrading and embarrassing. After taking ella one, within a few hours I felt very tired, had no energy, my boobs were tender and sore for about 2 months. Was constantly eating, wanted sugar all the time. My skin broke out in really painful hard spots on my chin, which take ages to disappear. My stomach was bloated all the time as if it was about to burst, was peeing constantly, honestly thought I was pregnant. Had a 2-day period which was heavy and didn't last long. Was still worried after a month of waiting, my period is finally here, thank goodness. Always use protection xxx."

For Emergency Contraception "I took Ella about 30 hours after unprotected sex. I didn’t get any symptoms after it apart from being very tired. I didn’t think much of it until my period was late... I was convinced that I was pregnant, I was a mess! Waiting, waiting, waiting until it finally came 19 DAYS LATE! I was a ball of worry for 19 days, but the relief was overwhelming. So if anyone else is in the same boat as I was, just give it time and try not to worry so much, or you’ll drive yourself crazy. Ella does work, but it will most likely mess with your cycle, so do expect that."

For Emergency Contraception "Had unprotected sex in my fertile period but too late at night to go to the chemist. I ovulated in the morning after unprotected sex (I get ovulating pain), so took ellaOne later that day. Made me very tired and feeling sick. Then, two days after, I got the weird heightened smell like you do when pregnant, and that dull, fluttery period achiness. I was convinced it hadn't worked and read that it just delays ovulation, which has already happened, so in my case might not work. Had a constant fuzzy uterus feeling. A week later, I got a stabby brief pain on one side and thought, right, this is it, it hasn't worked, and I've just had implantation happen, but tested negative and I got my period two weeks after. It was lighter spotting then got gradually heavier and more mucousy blood than usual. I guess that's how it works to stop the pregnancy, but bottom line it worked! I'm not ready for another baby! The side effects are horrible and completely mimic pregnancy symptoms, and the period that follows is very painful, but it works. From now on, I am going to be more careful as never taking it again."

So I took Ella around the time I thought I was ovulating. I had strange cramping pretty much all month after taking Ella, and then my period was late by exactly a week. During that week, I felt nauseous, tired, dizzy, and had an on-and-off headache with spotting, so I was convinced I was pregnant, but sure enough, I did eventually get my period, and it wasn't any heavier or lighter than normal.

I had unprotected sex about a month ago (yes, I know not very clever), but it happened, and my partner forgot to pull out. Anyways, I took Ella, around 56 hours after. I didn’t have many symptoms, I was just more tired, if anything. My period was supposed to come on the 8th, but instead it came today on the 14th. I was stressing out so much, I was sure I was pregnant. I thought I had most of the symptoms, even felt nauseous on some mornings, and my late period wasn’t helping. I took 2 pregnancy tests that week, and both came out negative, so I’m just glad that my period is finally here. Try not to worry, the pill did its job, but it does mess up your cycle, which is why my rating isn’t very high. Definitely going back on BC after this."
