For Emergency Contraception "This page has been a godsend for me the past few weeks so wanted to share my story to put anyone else in the same boat at ease. Took Ella One roughly 13 hours after an accident with a condom! On Tuesday 30th lo and behold, this was in my fertile days. Period was due 20th Feb... several pregnancy tests... I was doing one a day, I was that worried!! 7 days later my period has finally just come on and could cry with relief. No side effects whatsoever after taking the tablet but roughly 2 weeks ago to this day I have been feeling bloated, nauseous, sore boobs THE LOT. I was convinced I was pregnant. If you have anxiety, taking this tablet will make you worse with worry BUT it is common for the pill to make your period late so try not to worry. Just come and read this page for reassurance"

For Emergency Contraception "The length of my menstrual cycle is 26 days, always was regular. My last menstruation was on the 14th of February. I had unprotected sex on the 23rd of the same month and took the morning-after pill immediately. I again had unprotected sex on the 8th of March but did not take the pill since he didn’t ejaculate inside me. My period was due on the 11th of March (3 days before the expected period). I thought there was no chance of getting pregnant, but unfortunately, I didn’t get my period on the 11th as I expected. I was kinda worried. I didn’t experience the side effects of the pill - no nausea, slight bleeding, dizziness, nothing. After 7 days of the missed period, I took a home pregnancy test, and it was negative. I took another urine test after 14 days, also negative. Believe it or not, it took 51 days to get back my period. If your pregnancy test is negative, just wait and don’t waste your money on expensive tests, you'll get your period. Just be patient. I had to wait for 7 weeks and 2 days. Good luck, ladies."

For Emergency Contraception "I never usually write reviews, but this site really helped me stay calm while my mind went crazy. I had unprotected sex on the 8th of January, the day of my ovulation. Stupid me... I took it the next day and just thought I would get my period as usual, but that never happened. I started to get pregnancy symptoms - nausea, tender breasts. I was super scared... my period was due on the 23rd of January, it never came. I did a thousand pregnancy tests that were normal. I even panicked that I was infertile. Then, on the 4th of February, I got my period 11 days late. I’m so relieved... EllaOne works, just trust the process..."

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 "So I took Ella One after unprotected sex on March 24. I took it less than 24 hours after. The first week I was feeling really bloated, dizzy, however, it went away. On the 16th of April, I started spotting, and on the 19th I got my “period,” but it was so different than a blood period and not heavy at all. Around May 13, I started with period symptoms such as breast tenderness, dizziness, morning sickness, mood swings like normally, HOWEVER, it came 10 times stronger than ever in my life. I had those symptoms for the whole month. I was supposed to get my period on the 20th of May, and it was already 10 days late. I began feeling extremely bloated, and so I took three pregnancy tests. All negative, so I kind of felt relieved, but I was still feeling off. I stopped with the breast tenderness finally but was still feeling bloated and nauseous. I was sure I was pregnant until today! After 50 days, I finally got my period. Ella One works, but it also makes your cycle/hormones go crazy. Don't take it if you have anxiety."

For Emergency Contraception "EllaOne is a hormonal pill. By taking this drug, you are putting hormones into your body to delay ovulation or prevent an egg from implanting. Any drug that is strong enough to do that is strong enough to mess with nature's natural way of regulating a healthy menstrual cycle, so ladies, if your period is late, it's fine! Especially if the pill has worked and your ovulation has been delayed, it's only logical for your period to be late. Even if you find your period is early after taking the pill and the next one is very late, again remember what I said about the hormones, that too is normal. By the second week after I took the pill, I was surer than sure that I was carrying. I had sore boobs, backache, nausea, my period was late, I was moody, and most of all, I was fatigued. This is due to all of those hormones. These symptoms are all part of how the pill works, and sure enough, my period finally came."

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 "I just wanted to comment on my experience with Ella in the hopes that it may bring some comfort to someone. I took this emergency contraceptive pill 11 days into my normal 28-31-day cycle. Initially, I had no adverse side effects, but two weeks later, I started developing bloating, back pain, nausea, swollen and sensitive breasts-the whole lot. I was convinced I was pregnant. My period was late. Three negative pregnancy tests and 30ish days later, my period arrived on day 56 of my cycle. So it worked, but it pushed my cycle back drastically and far more than the one week it suggests."

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 "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 "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 "Had unprotected sex on 12th July. Fertile window started on 14th, according to my app. Took Ella one on 16th. Started to read literature and really panicked. Had every pregnancy symptom after taking it, even though my rational head was telling me it was too soon to develop symptoms. I was queasy, had a heightened sense of smell, metallic taste in my mouth, raised temperature, and awful anxiety. This went on for about a week. I then developed cramping in my lower back about a week after taking the tablet. Convinced myself it was implantation! Then things settled down. Period arrived today, a day early. Such relief. This forum was a godsend for keeping me sane. Thank you to all those people who have posted. It helped!"

For Emergency Contraception "I would like to share my story, maybe I can help someone freaked out like I was. Took Ella within 12 hours of UPS, right before or on the day of my ovulation. I was scared it wouldn't work. First symptom was the complete lack of any mucus. Then, a few days later, ovary cramps, uterus cramps... on and off. I was sure I had implantation. Again, a few days later, tender breasts, nipples, pain in my thighs, feeling bloated, etc. Read everything on the internet, panicked like hell. Then yet a few days later, nausea. By this time, I was going crazy, sure I was pregnant (in a fairly new relationship...). My cervix was way up and soft, creamy mucus appeared. Other symptoms kind of subsided, mood swings, breast tenderness, and backache remained. Took a test a day before the expected period, negative. Then it came on the day it was supposed to. I've never felt more relief in my life! It was a bit shorter than usual, but quite heavy, so I hope I am good. Test today also negative. Will check once more to be sure."

For Emergency Contraception "I thought I’d share my experience with Ella emergency contraception. We had UPS (unprotected sex) on the 4th of June. The 5th of June was when my ovulation days started, so I took Ellaone within 12 to 24 hours. I took an ovulation strip to ensure I’m not ovulating, my strip showed negative. I had no spotting, no nausea. I was due on my period around June 24th, I spotted ever so lightly on the 1st of July, just pink. I stupidly googled it, and implantation bleeding came up. I got an ovulation test kit (mostly because it came with lots of pregnancy tests), the pregnancy test was negative. This then got me questioning why my period never came. I don’t know if anyone has ever done this, but I decided to monitor my LH levels the whole month that I had Ellaone. PEAK positive on the 4th of July. I know you can’t ovulate when pregnant, so I waited. I started spotting on the 16th and have only started bleeding properly since the night of the 19th. Stay safe. It’s not worth it. Ellaone needs to be clear, it’s not a “delay by a few days.”"

For Emergency Contraception "I'm a bit worried. I took the ella tablet about 4 days after unprotected sex, and I felt fine. About a week before my period is due, I normally experience mild PMS symptoms, but for some reason, I'm experiencing nausea, cramps, sensitive to certain smells, etc. My period was due on the 4th of September, and she has yet to arrive. I've taken two pregnancy tests, both negative, so I'm pretty confident I'm not with child. I'm just worried that this tablet has done more damage, especially after reading that some people have had terrible experiences with this tablet. I know some people said it can delay your period up to 10 days, which is normal, but I'm also seeing people have said it's been 20 plus days and nothing. So, so worried."

So I took the pill 13 hours later. I suffer from health anxiety, so was worried sick that the pill was going to make me ill. It didn’t! I was on the 9th day of my cycle, so I knew I had to take it. Felt a bit nauseous on and off for 3 weeks, but that could have been me looking out for it? Period finally came only 2 days late. Relief! So really I wasted 3 weeks worrying and Googling, I didn’t need to, so just chill and it will be ok."

My period was 2 weeks late, and I suffered the worst cramping and nausea, I thought I was pregnant, so I did multiple tests and they all came back negative. I got my period finally, but it was a lot lighter than usual and shorter. Finished my period, then 6 days later had another period, but this was over a week long. It’s messed up my cycle ever since, my periods come at weird times now."

For Emergency Contraception "The only thing that kept me sane and not worried about my delayed period is reading all your comments here on this site. So I told myself I owe this site my experience once I get my period. I took Ellaone twice - once last July 27, a few hours after unprotected sex, and I had my period a week early. Then the second time I took it was Aug 15 - 4 days after the incident (I almost forgot about it). I didn't have migraines or any nausea or vomiting. I have anxiety issues, and I find it heightened my anxiety. I had a lot of white and yellowish discharge during the week of my supposed period, but it didn't come in the month of August. Then I had a lot of white stretchy discharge during my ovulation week. I used 4 pregnancy tests, all came out negative. After 6 weeks of stressful thinking, my period finally came, thank goodness. Ellaone works, but the complications and stress that I have to go through aren't worth it. I will not use it anymore. So be patient and try not to stress out more, as it will make your period delayed longer."

For Emergency Contraception "I am writing this review to share my experience with hopes that some will relate and ease their minds. I took it on 21st September, about 14 hrs after having unprotected sex. In the first three days, I experienced nausea, fever, fatigue, and hot flashes. The worst side effect was the anxiety. I have experienced panic attacks before but not this serious. I have always dealt with my anxiety successfully, especially when I can take action on what was worrying me. However, after taking this pill, all I could do was wait. I used to wake up at night feeling like I can't breathe with my heart pounding heavily. After 15 days, I went and did a pregnancy blood test to put my mind at rest a little, and it came out negative. My period should have started on 9th October, but it came today, six days later. I was so relieved! My advice to you women who are worrying and panicking is to try and relax. I know it's not easy, but Ella will probably have done its job well. Take care of yourselves xx"

I had sex 2 weeks ago on August 29th. It was my first time, and unfortunately, we had unprotected sex. My partner pulled out, and I thought everything was good. But I checked my cycle tracking app, and it turns out I’m ovulating. I started panicking reading stuff online. I took Ella within the next 24 hours. I didn’t really feel any side effects the days after I took it. Until a week ago from today, I started feeling nauseous after every time I ate. My breasts started to hurt, and I had mild cramps. I also had breakouts, which are normal for me before my period. I was convinced that these are all symptoms of implantation, but I really hoped that it was just pre-menstruation signs. My period was due on September 12th, but it didn’t come. I waited, and my period came late on the 14th, and I am SUPER relieved."

For Emergency Contraception "I know waiting for your period must be hard, and I personally waited for my period and read all these comments on this site. So my boyfriend and I had sex, and the condom broke. I panicked, like a lot. So we went to the pharmacy and got EllaOne after 2 hours. When I took EllaOne, I felt dizzy and sleepy, but not for too long. After 2 weeks, I started to have pregnancy symptoms like sore breasts, headaches, nausea. I swear I felt like I'm pregnant (but don't worry, it's just your hormones changing due to the pill). So I took 5 pregnancy tests, which came out negative, of course. I was terrified at first that I might be pregnant and the tests are not showing the exact results. So the only option I had left is to wait for my Red Aunty to visit me. Finally, I got my period a day early, but it's fine. My period is usually heavy and painful, nothing changed. Please trust Ella, she can do it! Lots of love and kisses!! Stay safe!! Your period will be here soon!"

However, I was meant to get my period 2 weeks after and didn't, so I assumed it did not work. I got extreme cramps and nausea, so I took a pregnancy test, which came back negative. Eventually, I got my period, but it was 3 months late and was very painful and heavy. It took around 6 months after that for my period to get back to normal. This emergency contraceptive gave me anxiety and uncertainty and caused me to stress. Although it did work, it isn't my first option."
