For Birth Control "I started googling this before I went on, and the majority of posts are negative - so I'm posting due to a positive experience. I started a month and a half ago after being on a combo pill for my entire life. So far, no issues, no weight gain, the only kinda weird thing is that I haven't gotten a period. Don't hate it, but will probably think I'm pregnant constantly because I'm so paranoid that way. LOL. No side effects so far aside from a bit of cramping!"

For Abnormal Uterine Bleeding "I was prescribed Errin as an alternative birth control because of having high blood pressure. The first 3 months were normal with my period lasting about 5-6 days. On the 4th month, I started bleeding profusely! I would bleed through heavy pads in 3 hours. The bleeding was full of huge clots. I lost so much blood that I was pale and required to come into the doctor's office for a checkup. The cramping was unbearable. There is no way this medication is worth the pain and money it costs in feminine products. The birth control works in preventing pregnancy because who would want to have sex with you when you are bleeding through your clothes! Terrible experience."

For Birth Control "Before I got on this pill, I looked up the reviews and was terrified from all the terrible things I read, but my gyne highly recommended it for me, and I’m happy she did. I’ve been on this pill for about two months now, and my experience has been great. Before getting on this pill, I would have terrible heavy periods that came along with cramps, acne, tender breasts, and mood swings. I have not gotten my period at all since starting it, only spotting with minor cramps. And I have not had any other terrible side effect. I would say give it a try because not everyone’s body is the same."

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 taking Errin for a week now. I started it the first day of my period. I usually have a 2-3 day period, but it stayed on for 6 days, it wasn't heavy. I get emotional due to the pill, I have lost weight, and I also notice my bottom is getting rounder! I'm experiencing light cramping, my hair is still intact, and no acne. I will follow up with you guys in about a month if there are any changes..."

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 am 22. I’ve been using Errin for 5 months. I started taking it 3 weeks postpartum. I don’t have my period ever, whether I take BC or not. My doctor said I had endometriosis, but I mostly use it for birth control. The only side effects I have are I feel super tired and lazy, and I have period-like cramps at the beginning of each month. I really like this, it does NOT cause me mood swings or anger like other BC has. The only thing I don’t like is remembering to take it each day at the same time. Other than that, it’s great for me."

For Birth Control "I'm 42, started this pill as a birth control method and also to hopefully reduce my heavy monthly periods. Two months in now, and my experience is horrible! I have one week left of pills, and I'm not going to continue to take them. First month started pack on Sunday after my period was finished. After another seven days, approximately of taking the pills, I have another full 6-7 day period. Then after that, around day 21 (which should have been when I was supposed to get my period), I got it yet again. I'm on pill pack two now. I'm now due for my period. I've had breast tenderness for two weeks and horrific cramping every evening (I take the pill in the morning), accompanied with nausea. Side effects make it hard to tell if it's the pill or pregnancy."

For Endometriosis "I’ve been taking Errin birth control pill for about a month now. Overall, it’s been really good! I haven’t had the spotting everyone complains about, and I have not had any cramping either. I normally have really terrible periods, so I’m hoping this birth control can either stop them completely or lessen the pain. The first week or two, it gave me really bad headaches (not migraines, just headaches), but those went away after about week two. I haven’t noticed any weight gain either. I feel like the medicine maybe gives me slight mood swings, but I can recognize them pretty quickly. Unfortunately, I’m not seeing any improvement in my skin."

For Abnormal Uterine Bleeding "Prescribed because fibroids and polyps (and probably pre-menopause) made the period flow unbearable. CONS: -If I don't take the pill at exactly the same time every day, I have 4 days of medium flow between cycles. Happened 3 times. Can't even be 20 minutes late or early. Felt like 3 periods in one month (every other week). -Cramps much worse than before. Still happen between cycles too. Often need Tylenol mid-sleep. -Clots huge unless I preemptively take Advil every few hours. -Breasts sensitive to the point of aching sometimes. -Period can be a week earlier or later than the previous one, so planning is impossible. PROS: -Actual period flow is slightly more manageable than before. -Spotting between cycles much less (sometimes not at all) unless I screw up my dose time. SUMMARY: If I take the pill on time with 100% accuracy, the period is slightly better. But my quality of life feels like it has declined due to the stress the side effects have added to it."

For Birth Control "I am 29 years old, and Errin gets an absolute no from me! After one week, I have had severe cramping for days without bleeding. Bloating so tight I can't move and very hard to get rid of. Headaches and hot flashes. Nausea spells throughout the day. The doctor recently told me I wasn’t a candidate for an estrogen pill and prescribed me this. However, I have never experienced any side effect worse than this pill: stay away!"

For Birth Control "Started Errin due to migraines from combination pills. Errin gave me cystic acne that does not respond to any treatment, which is very annoying, but I’m dealing with it because this is the only BC I can tolerate. Starting in May, I had a period at the beginning of the month and the end of the month, both 5 days long. (Pretty normal) No period the whole month of July or August, then 2 in September. One lasting 5 days and the other lasting 8. No period in October, and one in November. They consist of heavy clotting and very dark blood. The cramps are very uncomfortable. I also have constant breakthrough spotting, which is enough to fill liners. Very inconvenient, but this is what I’ll continue with."

For Birth Control "After a nightmare experience with an IUD, my doctor put me on ERRIN 0.35 strength birth control pills. I’ve been on it for two weeks now. It has improved my mood. I haven’t experienced any mood swings so far, I’ve had some spotting, but not heavy. I have been experiencing some headaches, cramping, nausea, loss of appetite, and exhaustion. I’m trying to hang in there because I do love the fact my mood has stabilized. The main thing I worry about is how tired I am. I feel very drained and bloated. I’m going to give it at least 3-6 months to prove to me, so I will be back with an update around then."

For Birth Control "I switched from the combo pill to a POP (progesterone-only pill) because of my migraines, and the only side effect I've had so far was a little bit of cramping the first day I was on it. Surprisingly, it hasn't made my acne worse, and I haven't noticed any crazy weight gain. I love that I skip my periods, and I haven't had any weird spotting yet like a lot of other people have reported. Very happy with Errin!"

For Birth Control "I've been taking this pill for 4 days and already want to throw it away. The biggest side effect is the cramps. I've literally had waves of pain through my stomach that feel like contractions since I started this! I feel like I've been in labor every day since I started taking these! Also very nauseous and bleeding heavy! Please, please, please pay attention to the reviews! This stuff is terrible and not worth the pain!"

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 Abnormal Uterine Bleeding "Been taking it for almost 3 months due to abnormal bleeding with no underlying causes. I've had a transplant, so the mini pill is my only option. I wouldn’t say Errin is awful for me yet since I’ve only been on it for such a short time. I can say though, I used to have severe cramps, but on Errin, they are very, very mild (so mild Tylenol does the trick). My periods do last longer (7 days), and the little brown spotting that occurs is a bit annoying. Hope my body responds well so I can stay on it."

It's been causing problems with my husband because sex is just not in the books for me. I'm moody, cramps all the time, headaches...it makes me sick. I just want my tubes tied."

For Endometriosis "Due to blood clot and diagnosis of autoimmune clotting disorder (anti-phospholipid syndrome), I had to be put on a non-estrogen birth control to help with my endometriosis. The pill has caused me to spot just about every single day, and I have been on it for over 6 months. It has not been able to control the cramps, and I have to have 800 mg ibuprofen on hand at all times. It has cut down on my 7-10 day very heavy period, but since I spot every day, not sure if it's really helped with the blood loss and anemia. When I started, I had just about every symptom of pregnancy, but I was not pregnant. This went away after about 1 month of use. Unfortunately, this is my only option at the moment, so I'm kind of stuck with this."

For Birth Control "I'm on month 3, and at first I had no side effects because I had just gotten off the depo shot. But this month I'm having mood swings. My face is breaking out, and I've always had nice, clear skin, and so far I've been bleeding 8 days straight and cramping every day as well, which I've never done! I'm seriously thinking about getting off this pill or taking nothing at all. I'm tired of all these toxins in my body doing me harm!"

For Endometriosis "I had god-awful endometriosis. When I get my period, I have cramps so bad I cannot function, diarrhea, and nausea. I started Errin to help fix this issue. The first month I didn’t bleed but had god-awful cramps (per expected). After the first month, my periods came twice a month and lasted about 7 days. My cramps weren’t as bad as when not using birth control. 8 months later and it’s still the same. I’m actually getting off Errin because my active lifestyle isn’t really fitting with having my period half the month. With Errin, my acne skyrocketed too. My chin and cheeks have never been so broken out in my life. I used to never wear makeup, and now I can’t bring myself to be in public without it. I’m glad I have to wear a mask in public because of how bad my acne is. Altogether, I didn’t get pregnant, my cramps got slightly better, and my acne is uncontrollable. Wouldn’t really recommend."

For Birth Control "So, I'm 23 years old. I went to the doctor not only for birth control but for something to control my terrible menstrual cycle. I would bleed for 7 days straight, heavily at that. I was first put on Depo, which I absolutely adored! No periods, no terrible side effects like most people warn you about. Well, after 2 years, my doc tells me it's not good to be on Depo longer than 2 years, so I switched to a pill. I smoke, and at this point in my life, I am not ready to quit, so I take progestin-only pills. At first, starting Errin, I spotted for about 2 weeks, but I figured that was because of not having a period for nearly 2 years. Since then, I have a period every month, and while they only last about 4 days with moderate bleeding. Cramps are bad!!!"
