For Birth Control "I’m on month 4 of Slynd and was prescribed this due to extremely heavy/painful periods and anemia. I’m in my late 40s and have had these issues since I was a teenager. Over the years, I have tried nearly every birth control pill available and stopped each due to varying side effects (migraines, mood swings, bloating/weight gain - you name it). I was hesitant to try yet another BC pill and was actually going into my doctor to talk about getting a hysterectomy just to be able to get my quality of life back. I agreed to give this a try first since it doesn’t have any estrogen. In the first 2 months, I had significant breakthrough bleeding (I think I bled for three weeks straight). That said, I am so glad that I stuck it out… Starting the third month all of the spotting and bleeding went away, and I have had virtually no side effects since then. Add to that, my period has pretty much disappeared over the past couple of months which is amazing. So glad I gave this a try. Life-changing."

For Birth Control "I have Stage 4 endometriosis and the last pill prescribed to me - Jencycla, made my endo flares worse - I was in pain 25 days in a month! As soon as my doctor switched me to Slynd, I felt better right away. I was able to lose weight and I didn't have recurring cramps. The only downside was the on and off spotting during my first two packs and not having my period for the first month of using Slynd. I had my period starting the third pack, but I didn't have severe cramps that would last me 3 days and my period wasn't heavy. I will continue to use Slynd and I'm glad that this is helping me ease my endo pain - I know this is just a band-aid, but being pain-free for 3 months is like getting 3 years of my life back!"

For Birth Control "I just started month 3 of this pill, and I absolutely love it. I was taking norethindrone before, and I was getting mild acne (never had acne before in my life), heavy irregular periods, and slight weight gain. On Slynd, my face is back to normal with only the extremely rare single pimple, and my period is almost non-existent. It always comes on day 3 of the green placebo, lasts 3 days, and is little more than spotting with mild cramps and tiredness. I haven't gotten pregnant yet, so it seems to be working on that front as well. I started to take birth control as an effort to control my migraines. They're not gone, but I have noticed any hormonal related ones I get after my period are much less severe. I haven't noticed any weight gain or loss with these, and my sex drive seems to be about the same as it was before as well. Obviously everyone's miles will vary, but this pill has been absolute magic for me so far. I hope it continues as is."

For Birth Control "I'm on my 4th month of Slynd. I switched from a pill containing estrogen because I'm 41 and get migraines (infrequently). Because I have endometriosis, I do not take the placebos. The first week I had minimal spotting and cramping (and was expecting far worse). Since then, zero cramping or spotting or endo pain! My acne has neither improved nor gotten considerably worse. But I went through a time in the second month where my skin was more oily than it had ever been. Also during my second and third month, I was dealing with really bad anxiety. Hard to say whether the transition to Slynd had something to do with it or whether it was situational. I was able to lose about 6 pounds by eating more mindfully and have not had a migraine since starting it. Overall, I am extremely happy with how I have adjusted to it."

For Birth Control "I've been on Slynd for over a month, and I already hate it. I'm 35 and have endometriosis with horrible cramps that put me in the hospital. I was in pain a lot, so I wanted relief and a better quality of life. While this pill already relieved me of the terrible endo pain and 7-day periods, my moods are so bad! I cry... A LOT... and for no reason. I'm having more anxiety, and I feel depressed. Also, I have a headache every day and am SO thirsty, my eyes are dry. Sleep has been rough... I can't get a full night's sleep anymore. I get easily annoyed and angry, like I blurt out what I'm thinking because I'm so annoyed. Also, I didn't get my period the first month, but I've been spotting every day since I started taking it. Honestly, I don't know what's worse: the endo pain before Slynd or my mood on Slynd. I have a free 3-month supply, but I don't know if I can take it anymore. I think it's doing me more bad than good."

For Birth Control "I wanted to see how everyone else that has still been on Slynd has fared? I just started my first month on this and started bleeding more than spotting for sure the second week into this pack. It hasn’t really let up! I called the doctor's office and they just said breakthrough bleeding and spotting can be normal and just try and continue. It’s really discouraging as I don’t want to experience this bleeding for the next two months or so to adjust to it. Has anyone else had their bleeding in between improve at all? I’m getting frustrated! I also have some light cramps, otherwise, nothing else, but the bleeding is very frustrating. Hoping it’s normal!"

For Birth Control "This medication has been life changing! I am 47 and was having horrifically heavy periods every month (sometimes more than once/month). They were causing me grief and wreaking havoc on my daily life. I had tried multiple pills before Slynd and was considering a hysterectomy. My doctor had me try it in a last-ditch effort, and lo and behold, it worked! Took a few cycles, but after about 3-4, my periods are gone! I might have one day every few months that I spot, but that’s it! Truly life changing!"

For Birth Control "I’m really enjoying Slynd! I was on Lo Loestrin FE and came off because of migraines and intense anxiety on placebo pills. My NP advised me to take this continuously, so no placebo, and my moods/emotions are so stable, and I don’t get a period! I had some very, very light spotting for two days during pack three, but nothing worth doing anything about. My skin has cleared up so nicely, and I haven’t gained any weight. I think it's worth a try if you struggle with panic disorder!!"

For Birth Control "I have been on Slynd for a few months now, probably around 7 months. My previous birth control pill gave me crazy mood swings and made my depression and anxiety worse, as well as making me extremely irritable. The first three months on Slynd were way better than my previous pill; however, I would experience spotting days or over a week before even taking the placebo pills. About 5 months in, I experienced breakthrough bleeding for 3 weeks. After that, it all went downhill. I find that at the end of the second week of my pack, my depression and anxiety hit an all-time high. Intense mood swings of high anxiety and vicious sadness hit and last until I take my placebos. Every pill affects everyone differently, but if you have a history of depression, anxiety, etc., you may want to use a different pill; I would not recommend this pill."

For Birth Control "I'm a month into using Slynd, and I have had no issues. Due to constant headaches and migraines, I switched from the combo pill to Slynd with the hopes it would help with my headaches. I've had no headaches since starting (although I have still had my usual monthly intense migraine, but I didn't expect birth control to fix that). My head feels much clearer (I'm not sure how else to explain it!) now that I no longer take a combo pill. If you have headaches/migraines and are looking for a birth control with no estrogen, I would highly recommend trying Slynd. I've had no acne, no spotting, no weight gain, and a drastic difference in the amount of headaches I have. We will see how the next few months go, but so far, Slynd has drastically improved my quality of life with no side effects."

For Birth Control "I have been taking Slynd birth control pills for 4 months total, just starting my 5th. I used to have a regular 3-day period with severe cramps. I have had nonstop spotting since beginning this birth control. My cramps are gone, but I have been spotting for almost 30 days straight. It has been a nightmare from the start."

For Birth Control "I’ve had heavy periods and terrible acne for most of my adult life. I was on Yaz for 8 years with no problem. Once I hit 31, I had terrible mood swings and went into a deep depression. I got off Yaz and felt like myself again. The acne and heavy periods came back, but I was terrified of getting back on a pill with estrogen. I tried every holistic remedy you could think of, but it only got worse over time. At 34, my doctor recommended Slynd, so I decided to give it a try. Within a few weeks, my acne completely disappeared. I had irregular bleeding for the first two months accompanied by breast tenderness, but since then, my period has completely disappeared. I’ve been on it for 7 months, and I haven’t experienced any other side effects. No weight gain. No mood swings. I will add that it took about 3-4 months for my body to fully adjust to it (I had some random spotting here and there). Highly recommend!"

For Birth Control "I have endometriosis, and this pill was recommended to me because I was having a lot of breakthrough bleeding and spotting between periods, and I also have a history of cysts. I’ve been on many pills throughout the years, and this by far has been the worst experience. I would not recommend this to my worst enemy. I started bleeding immediately the first day I took it and never stopped for almost 2 months. The doctor said to give it 3 months for my body to adjust, but I couldn’t do it. I gave up about 2 months in because I was also having headaches, bloating, anxiety, trouble sleeping, and severe mood changes. I did not feel like myself and was either crying for no reason or raging in anger with both, not like me. I stopped at the end of December, and my periods have still been off. I bled from mid-January to mid-February, and now in March, I didn’t get my period at all. I suspect this is now my body re-adjusting from being off this pill, so beware if you’re going to try it."

For Birth Control "I started the first pack of Slynd during my period, and I had spotting after 2 weeks of the pack for about a week, and then I got my period with the placebo pills, as expected, for about 4 days. During my second pack, I had about 4 days of spotting and some bleeding, but then I skipped my period at the end of the 2nd pack (during the placebos), and then on the 3rd pack, I didn't have any spotting or breakthrough bleeding until 2 days before the placebos of that pack. So I was clean for about 5 weeks straight, which was exciting. But now I am on my 4th pack, and I had heavy breakthrough bleeding only a week after my period ended, and I am still waiting for the spotting to stop a week later. The nurse at my gyno practice said it could take up to 6 months for my body to get used to the pill. It has been pretty concerning, given that naturally my period cycle was very consistent and regular. I haven't had any other side effects from Slynd other than the irregular bleeding/spotting."

For Birth Control "I was switched to Slynd after taking Sprintec for 3 years due to high blood pressure. I unfortunately had a bad experience taking Slynd. It gave me the worst cystic acne (my skin was clear before). I had a lot of spotting during the first pack and horrible cramps. My period was very light, but the cramps were so bad during it I contemplated going to the hospital. The second pack, I also experienced horrible cramping that would wake me up at night, but my period never came and still has not. I’ve gained 20 pounds since starting Slynd without changing any of my normal daily habits. On top of all this, my insurance refuses to cover it, and it is very expensive ($250 a pack)."

For Birth Control "I started taking Slynd to help with my heavy periods. I have 3 small fibroids, and I hoped this would lighten my flow until I could figure out my surgical options. I started taking it on the first day of my period, and the first thing that happened was bloating that was so intense I could barely put on pants. I had the WORST period of my life. The cramps were debilitating. After about 10 days of pain and cramping, things slowed to just some spotting, but after a week of that, my period came back HEAVIER AND MORE PAINFUL than I’ve ever experienced in my life. I was literally filling up an overnight pad every 45 minutes. I stopped taking the pill after 18 days of starting because the side effects were unbearable. I’m 5 days off it, and my body is slowly returning to normal. Don’t make the mistake I made by ignoring the low approval rating for this medication. The side effects are horrific."

"Okay, girls. I’m here to give you a positive review. I started this medication because I had awful periods. I’m talking cramps to where I would have to miss work, and I felt like I was dying. I told my doctor I wanted to skip periods, and this medication and the mini pill are the only pills I can take with other medications I take. For the first 3 months, I spotted every day. Within those 3 months, I may have had 1 period that lasted 1 day, with no cramps starting the second month. As of 2 weeks ago, the spotting ceased. My mood is better, and I’m losing weight. I love it. I’m thankful for the manufacturer coupon because my insurance would not cover it. Starting my 4th pack tonight. Don’t be scared to try this. Give your body at least 3-4 months to adjust."

For Birth Control "I am halfway through my 3rd pack of Slynd pills, and so far, I really like this one. I was on norethindrone (Mylan) for almost a year and had headaches, weight gain, and mood issues. I stopped for a month, then got on Slynd. I started it the first day of my cycle. I started my second pack and had spotting for 2 days (I'm assuming it was a period) and slight cramps. My third pack, same thing, I had spotting the first day of the pack (when my period was to come), and slight cramps and felt like I had a period with mild symptoms. I'm hoping it stays like this, but I know I'm still adjusting. No weight gain so far, no acne, and my mood is much better than with my other pill. I get it through Nurx, and my insurance covers it, luckily, because so far, so good!"

For Birth Control "I am into a month and a half. At first, I had spotting here and there. The past few days, it has been almost a normal period. The doctor said it could take up to 3 months for my body to regulate to it. So far, I have noticed more breakouts, slight cramps, and some depression/anxiety, however, my body is adjusting, so that's to be expected, especially since I already suffer from both. My doctor has me skip placebo pills and said I won’t get my period anymore in a few months by doing so. I’ll be back to update after a few more months. Just remember, it takes your body time to adjust (could be a few months). Nothing unbearable."

For Birth Control "Just starting my third pack of Slynd. I haven’t had any spotting or bleeding since I started. I skipped the placebo pills on my first pack and took them with my second pack, but haven’t had any period symptoms, which has been strange. I was put on Slynd due to my blood pressure being a bit high, so my doctor said this pill, Slynd, does not affect it as much as other birth control pills. After reading some of these comments, I’m not sure that she was truthful in that statement, but so far it’s been okay."

When I’m not bleeding, I’m spotting, and I’ve given it way more than enough time for my body to adjust.

For Birth Control "I am now on my 4th month of Slynd and love it. I struggled with horrible cramps, heavy flow, and terrible hormonal acne before Slynd. Cramps and heavy bleeding have completely stopped, but my acne persisted up until now. The first few months my acne was very consistent (new breakouts almost every day). However, after starting my 4th pack and trying a healthier diet, my acne is clearing up and looks a lot better than it has on other BCs. I have had no weight gain, and I feel that my moods are a bit more stable. The only issues I had were pretty consistent spotting (it felt like I would be on my period more than I wasn't), but I've noticed that this reduces each month that you're on it. Slynd is the only birth control that I've tried where I cannot feel the side effects every day. I have probably tried 7 different types of BC, and this is the best one yet (besides the fact that my insurance will not cover it)."

"I've been taking Slynd for 4.5 months. So far, this has been wonderful! I had extremely heavy periods. I was bleeding for 12 days every month, and 5-6 of those I was changing a menstrual cup every 1-2 hours, even at night. My ferritin was down to 5. This was my last resort before I figured I'd end up with a hysterectomy. The first two and a half months, I had significant spotting and light bleeding. After that, nothing! No other side effects. My moods are stable. I don't have hardly any anxiety anymore. No weight gain. No headaches. I hope this continues to work this well. It's been a lifesaver!"

For Birth Control "I am on my 3rd pack of Slynd. I used to have an extremely painful period prior to taking this medication. I have never been on birth control before this, and my OB-GYN prescribed this because I can’t take estrogen due to high blood pressure. My first period after the start of this was very light and less painful, but I have been bleeding ever since that period. I can say that I have been bleeding lightly for a month now since starting the second pack of Slynd. I really hope the bleeding stops because it seems to be reducing now. I read other reviews, and I have faith that it will stop soon. I haven’t experienced any weight gain, and my mood has improved. I was not sad on my last period. The only thing bothering me right now is the spotting. I’ll be back to give an update."

For Birth Control "It’s effective against pregnancy because spotting, cramping, bloating, and discomfort happen for several weeks. Also, my anxiety and depression have increased since starting Slynd. I’m not sure if it’s because I haven’t been on it for as long as many other people (I started using Slynd November 19th) - but I don’t want this to keep going throughout months to the point where I throw out the pill and just use another form of contraceptive. My doctor recommended this to me because he thought I was very sexually active - even though this pill stopped me from being sexually active completely because of the amount of periods I got for a long amount of time. Not to mention I kept getting cystic acne and acne in general - and I’ve been gaining weight as well."
