For Abnormal Uterine Bleeding "Okay, so I have been on this for a week now. My face hasn’t broken out more than usual. I have insanely irregular periods, and literally the day after starting this, my period ended, and it hasn’t started up again. Before, I would have maybe two days of no period, and then it would hit me like a freight train again. My body feels much better than it has in years! Again, I have only been on this for a week. I haven’t had any weight gain or random spotting... yet? Idk. Before I got put on this birth control, I literally bled, had intense cramps, mood swings, and migraines pretty much daily. I’m not saying it’s good for everyone, as everyone’s bodies are different. It has worked wonders for me. I will post another review as time goes on. I also haven’t had any issues with my hair falling out or being dull. It’s so nice to not be so damn hormonal every day. I feel so much better health-wise now. I think it’s honestly balancing out my chemicals, but I’m not a doctor."

For Birth Control "I have been on Errin for about a year now. I chose it because I had just had a baby and wanted to be able to breastfeed. I've had a great experience with it. No moodiness or weight gain. I've been on other birth control pills that were combo ones, and those I could tell changed me emotionally, but I haven't had a problem with this one. I can't relate to others who have mentioned having a period for 3 weeks straight because my period didn't come back for about 9 months after having my son. But now I seem to have a period every other month, and it's only about 3-4 days max and not too heavy. I would recommend it to anyone, especially if you are sensitive to meds or just had a baby and want to nurse."

For Birth Control "Like stated before, everybody handles birth control differently! For me, it has significantly improved my mood! I haven’t had the weight gain, if anything, I’ve lost. Periods can be a little off or nonexistent sometimes, but nothing crazy. (I enjoy the break from a period, lol.) Give it a try!"

For Birth Control "Was on the depo shot for 2 years. Everything was okay the first year, but I switched because my last 6 months on it was terrible! I had no period for 4 months, it made my depression worse, I was always bloated, gained over 30 pounds, had nipple discharge, and was struggling to stay self-lubricated during sex. I decided to switch to a pill, and my doctor recommended Errin due to my background of migraines. I have been on it for almost 4 months, and I got my period back a month into it. I am no longer constantly depressed or constantly bloated, it doesn’t seem to give me rapid weight gain (I lost two pounds since starting), no more nipple discharge (my breasts grew half a cup size, actually), and I have no dryness issues. I finally feel normal again. I would give it a 10/10, but I haven't been on it long enough. I would recommend anyone who had a good experience with depo that turned horrible to try Errin out."

For Birth Control "I have been on Errin norethindrone tablets for almost five months now and have liked it a lot more than regular birth control tablets. I gained a lot of weight on birth control with estrogen and have not on Errin, which I liked. But, it has not helped acne like my old birth control. I also haven't had a period since the first week I took Errin, which is somewhat concerning, but I'm not pregnant, so I assume it is just my body getting used to the medication. Errin has not affected my mood or mentality."

For Birth Control "I never post here, but after the nightmare this BC put me through, I had to. Started Errin in 4/20, the doctor refused to give me any more combo pills due to high BP. I was put on Errin. 6/20 came around, I noticed my periods were lighter, but my cramps were crazy. I dealt with it and thought it was that one time. THE NEXT FEW MONTHS are a BLUR. I was out of it most of the time when my period came around. Pain in breasts, moody, 30 lb weight gain, bloat, nausea, dizziness, headaches, but THE PAIN in my ovaries back and uterus-out of control. I stayed on these for a year, until 4/21, I couldn't go to work because the pain went from happening during my period to EVERY DAY. I was miserable and felt majorly depressed. I was scared. When the doctor suggested I switch to Slynd after not finding anything wrong, I decided to give it a go, thinking Errin wasn't the problem. 3 months later, the pain is gone. I should have known. I went to the ER for this 5 times. I do NOT recommend. If in doubt and you feel off, check your BC."

For Birth Control "Been on this for 3 months now. Only taking this pill because I am currently breastfeeding and have no other options, really. I've had probably 6-8 periods since I've started this birth control. I'll bleed for 6-9 days, stop for less than a week, and start the process all over again. The bleeding is heavy. I've gained some weight. The acne is terrible and extremely painful. I've developed constant cramping and occasional heart palpitations. Oh, and the hair loss. My god. I have to empty my brush 2-3 times when I brush my hair, and clumps come out in the shower. The worst side effect I have encountered on this pill is the moodiness. I get so angry for absolutely no reason and catch myself freaking out over the littlest things. The side effects of this pill are terrifying. I've been on numerous different pills as well as the depo over the last 11 years, and this is by far the absolute worst. I would never recommend."

For Birth Control "I started taking Errin over one year ago when my doctor recommended me to get off the combination pill because of migraines, my age, and high blood pressure. All I know is that since I’ve been on it, I’ve gained 10 to 15 pounds that I cannot lose. I work out, I eat right more than I ever did before. I don’t know if the pill is contributing to it. I also have mood swings. I normally do not get my period, but though last month I got one, and it was pretty heavy. I do get the breast tenderness, so I’m not sure if I want to stay on it or not. The weight gain is what’s really bothering me."

For Birth Control "I gave Errin birth control pill a whole year to settle in with my body. I gained weight, have had irregular periods, including one that leaked all over my white pants (talk about being 44 and feeling like you are 14!), fatigue, you name it! I also have had issues with inflammation and an undiagnosable lymph node issue in my neck that happens to flare up just once a month. I’m convinced it’s due to this pill. Stopping it today after talking to gyn."

For Birth Control "Wish I read the reviews before taking Errin. I have been on Errin for 15 months and stopped taking it a week ago due to severe migraines, weight gain, moodiness, and decreased interest in things that I usually enjoy. My sex drive has decreased, and I have little or no interest in my husband. I could not figure out why I was so upset over small things, and he even asked me to look into alternative methods of birth control. PLEASE do your research. It's not for everyone."

For Birth Control "I switched from the patch to 'Errin' in mid-February by my doctor as she was worried it was affecting my blood pressure as it was too high. I've been on it for 3 months and have had inconsistent periods. 1 being a week and a half long, spotting a few days after I had just had it, not getting a period at all the following month, and now receiving a very light period (possibly spotting) for 5 days already. During these 3 months, I have gained 10 pounds although I have not changed my healthy eating habits and actually added a few workouts during the week. I have noticed I'm moody or depressed throughout the day at work and at home a couple of times a week. Nice that my blood pressure has been normal, although I'm taking blood pressure medication as well. I'm currently switching to the patch again once I finish this pack since I'm not happy with the outcome. Hope this helps to whoever is seeking insight who has high blood pressure and is considering taking Errin."

For Abnormal Uterine Bleeding "I began taking Errin for a month, and I've had the worst experience ever with this birth control method. I have gained 20 pounds since taking it. There was spotting between my periods. I had extreme mood swings that were crazy ups and downs. I experienced headache, anxiety, and increased blood pressure. I don't recommend this b.c. to any woman who is thinking of trying the progestin-only pill. Yes, it is the mini pill, but I had a horrible experience. I will just deal with my adenomyosis and heavy periods w/o birth control. Never again!"

For Birth Control "I had my IUD removed due to weight gain (lost 10 pounds of water weight in 2 weeks after removal), and a month later started Errin in hopes that it would be a better fit... but I have gained weight again and feel pregnant all the time, it's a serious bummer. Errin really helped with my anxiety, though, and my skin is quite clear compared to how it was before. I would recommend trying it and just being aware of your symptoms if there are any. Unfortunately, I'm coming off of it starting today to lose this water weight again, uggghhhhh."

For Birth Control "I've been on Errin for about 7 months, and I have never experienced more painful period cramps. That is my only complaint while being on this birth control. Before starting this pill, I was taking Lo Loestrin Fe, and I experienced terrible acne, felt depressed and emotional constantly, and gained some weight. Although the cramps have been bad with Errin, I would rather take this pill than what I did before."

For Birth Control "I’ve been on Errin for five months now, about to start my sixth pack. The first few months were rough as my body got used to the hormones, as this was my first ever time taking birth control (21 years old). I bled for about a week every two weeks for the first four months, and now it seems that I’m back to a regular monthly period. I started getting acne almost immediately, with it peaking around the four-month mark. It’s slowly getting better with prescription medication. I’ve experienced minor weight gain, but that could just be a side effect of being in a relationship, lol! My partner and I don’t use condoms or the pull-out method and have sex pretty frequently (multiple times a week), and I haven’t gotten pregnant yet (knock on wood!), so overall I’d say this is really effective!"

For Birth Control "The worst thing I have ever experienced. Getting pregnant again would have been better than this birth control. I wasted 4 months of my life on this pill. I gained weight, hair loss, cramps, headaches more than I didn’t have headaches. Finally stopped it and all my symptoms have been subsiding. I’m sure it works differently for different people, but it was the worst thing I’ve ever done."

For Birth Control "I used to be on birth control for years to inhibit the growth of ovarian cysts. I stopped and was off pills for 6 years. Unfortunately, I am still very fertile, and as a single mom in a committed relationship, I did not want to have more children, especially since I will be 40 next year. I decided to try the mini-pill to avoid the effects of estrogen. This worked in that I didn’t get pregnant while on it, but it caused me pretty much every side effect. I developed acne on my face, my mood swings were crazy and very negative, my appetite greatly increased and I gained weight, I no longer had natural lubrication since my vagina became very dry, I noticed an obvious decrease in libido, and my breasts became very sore and tender the whole time on the pill. I did experience some very light spotting, but I wouldn’t have a problem with that if it weren’t for the other symptoms. Unfortunately, I’ll have to resort to another method of birth control. I had high hopes for this pill."

For Birth Control "I'm at the end of my 2nd month. First month was on the .25 dose. Gained 4-5 pounds in the first 2 weeks! I'm very petite and have been the same weight for 20 years, so this was a huge drawback. My doctor changed me to the .35 dose, and still the same weight but now more pimples and bled for 2 weeks. Also, I think this pill makes me feel kind of blah and empty inside. Could be environmental factors, but I think I'll be switching soon!"

For Birth Control "I really wanted to have a more positive experience on Errin, but it just wasn't a good fit for me. After a month of bi-weekly periods, I started spotting every other week, and as a result, it felt like I was constantly PMSing. I gained about 8 pounds of water weight, and I felt uncomfortable and bloated almost all day, every day. Lastly, I just didn't feel like myself on Errin. I would get very inconvenienced by small things, it made me very emotional, and it was even hard to get out of bed in the morning some days. It also kept my psoriasis breakouts pretty constant. I asked my doc if I could take some time off instead of starting a new pack, and within 5 days, I was back to a normal weight, my skin cleared, and I felt like myself."

For Birth Control "As much as I wanted to love Errin, this was definitely NOT for me. I have never been any lower mentally, nor experienced so many mood swings all at once. I started taking this birth control at the beginning of March, so for a month, it really just changed my appearance and mental health. Now I have acne all over my face, and it was never as bad as this. Also, I am gaining weight fast too, and I barely even eat. I just do not feel like myself, so if you have anxiety or depression, I would not recommend this birth control. I take .35 mg every day, so maybe it is the dosage and it's too much, but either way, I will not be continuing this pill."

For Birth Control "Every woman's body is different, how it responds to birth control. Some have no issues, and some have every side effect possible. For me, this pill, Errin, is THE WORST. I was on a combination pill, and my gynecologist switched me, thinking it was causing my high blood pressure, as some pills can do. I was on it since Aug 2019 and recently just switched back to the previous one I was taking-thank goodness! This pill made me sick, such as nausea, severe bloat, weight gain, spotting, and never knowing if or WHEN I would even have a period, major cramps that I've never experienced ever before-even when I entered adolescence, swollen breasts, and fatigued constantly. I understand this works for some, but definitely NOT FOR ME! I'm so glad I switched back, and now I feel back to normal after less than a week of being off of it. This is especially not a good one to take if you're like me and want to know WHEN you'll have your period."

For Birth Control "I was on Depo for about 10 years as a teen and into my early twenties. I gained 100 pounds, but I was okay because I didn't have a period and couldn't get pregnant. I got off of it about 10 years ago, had my son, and decided, now that he is 9, I'm done having kids, I want back on BC. My doctor said no to Depo due to my gaining all the weight before, and I am about to have bariatric surgery. So she put me on this. Since day 2, I have EXTREME cramps. Every day after I take the pill, I have cramps for hours. I never really had cramps for my period. When I am off of any birth control, I do get PMS, one week before I start, I get the mood change, I get very minimal crampy, like a 1 out of 10, and I get sore. But during my period, no cramps, my mood is fine. Well, this morning I started, and I want to scream, and my cramps are worse than childbirth. And I did that all natural. I spoke with the nurse about the cramps, and she said they would go away about 3 months into taking the meds. But I am not sure I am willing to wait 3 months."

For Birth Control "I have been taking Errin for three months now. I started taking the mini pill after contemplating using birth control again. My periods were terrible. I would bleed for 7 days, and I would bleed (TMI up ahead) probably a coffee cup full each period. (Thanks, DivaCup, for letting me track that.) I was left exhausted each time, I was flooding each month. I take my pill at the EXACT TIME every single day. I have an alarm set. I noticed that my breasts get really tender about a week before my period is due, but they hurt before I started taking it. I noticed that although I still bleed 6-7 days, the amount of blood is so much less! I used to have to wear a cup and a large pad during my first few days. I am so happy to have tried this pill. My periods are so much more manageable. Side effects: so far, I have gotten 4 pimples, I have also gained one pound."
