For Birth Control "Just finished my first pack and was nervous reading these reviews. I lost 4 lbs this month through my regular diet and exercise, and the pill did not seem to affect that. I do not have any acne, and my hair is planted firmly in my head. I have not experienced so much as a spot or cramp. The only thing I did notice was a headache that lasted for about 30 minutes the first day and slightly decreased appetite in general. I much prefer this over my previous IUD."

For Birth Control "I have been using Errin for about a year now, and honestly, I love it. Before Errin, I used a combined BC pill, and I had awful side effects. My limbs went numb, I had terrible headaches, I was very dizzy and nauseous. My healthcare provider recommended a POP because of my past experience with estrogen. Since being on Errin, I have honestly had no side effects. Definitely recommend this BC for those who can’t have estrogen like me."

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 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 "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've been using Errin for 1 month. I got used to taking it routinely without getting scared that I would forget by simply putting an alarm on my phone and stashing my pill card in my wallet. So far, only symptoms are major pimples all over my face, bad headaches that would last intermittently for 2 days, and tender breasts from time to time. My attitude is the same, and my husband and I are making love a lot more, and it's better than usual. I hate the pimples only because these pimples are not easy to go away. They feel more like baby boils, and I never usually have pimples... I always have clear, nice skin."

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 "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 took this birth control, and it made my mood horrible. I got so irritable and mean. Caused my armpits to get lumps and became very sore. I got pretty severe headaches. Woke up feeling hazy. Stopped taking it right away, and it all went away. Not getting pregnant is not worth the side effects. It made me miserable. Do not take this."

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 "So far, it has been okay. A lot of spotting and minor headaches. Less acne and no hair loss. I used to have very heavy periods every 20 days. I am on Errin, and the first month I spotted every day, I did this on combo pills too. Now, I have a period and then spot a few days. The days I spot are also from taking it an hour late. I'm on my third month now, and I am hoping it regulates everything. I noticed my face looks less haggard, and I am 43."

For Abnormal Uterine Bleeding "Terrible. I had taken a combo pill years before and had no issues. This gave me headaches, tender breasts, and irregular periods. I had two periods a week and a half apart, then one that lasted 10 days. I stuck it out to see if it would regulate things, but it didn’t. Never again. Switching back to a low-dose combo pill."

For Birth Control "Before taking this birth control pill, Errin, I was on a combination pill (Tarina Fe) for about 7 months. My gynecologist switched me to Errin because of the depressed mood. I've been on it about a week now. The first two days were a nightmare of mood swings, but it's evened out now. My biggest complaint is the number of side effects I'm already experiencing - nausea, dizziness, headache, severe fatigue, bloating, stomach pain. I'm also experiencing fever and chills. I will probably be talking to my gynecologist about this soon if it doesn't let up. I'll take the depressed mood over feeling sick all the time."

For Birth Control "I'm 42 years old. Omg, this pill makes me feel like I'm on my cycle every day. I'm assuming it's the pill. I've been on it for over two years now. 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 Birth Control "I was really scared to start Errin in the beginning, having read quite a few bad reviews, but I’m glad I did! It has been an effective, fairly non-disruptive method for me. Please remember that everyone responds differently to different methods and has different experiences. At first, I experienced some bad headaches that went away after about a month or so. My PMS was quite bad before starting this, and I haven’t noticed much difference either way after starting Errin. My periods became shorter for the first 6 months or so, but now they are back to my previous length of 5-6 days. Errin definitely messed up my previously VERY regular cycles, and now I often go 40 plus days between periods. I honestly really wanted it to stop my periods, but having them less often isn’t so bad. I do occasionally experience 2-3 days of spotting around ovulation, which isn’t very heavy and is definitely manageable. Overall, for me, Errin has been a good birth control method."

For Birth Control "I started this birth control about 4 months ago because I have a heart condition and can’t have estrogen birth control. In the beginning, it was fine, and I had slight headaches. After the first month, I started having clotty periods and severe breast tenderness 2 weeks prior to my period. It also gave me bad anxiety and caused some depression. I couldn’t function sometimes at work due to anxiety. I took it every day on time. I never got pregnant, but I recently had to stop it because anxiety and depression started to get bad for me, and I’m usually a happy person. This birth control didn't work for me, but it could for others."
