Slynd pill side effects

I’ve had nothing but cystic acne, heavy bleeding for 2+ weeks at a time, hair growth is still the same rate if not even worse.

I’ve tried pretty much every form of contraception within 15 years. Implant x3, injection, mini pills, copper coil. The hormonal ones gave me irregular periods and vaginal dryness and the copper coil gave me chronic BV. Since taking Slynd I’ve had none of this. Skin is fine, weight is fine, periods are regular, lighter, shorter. They do not align with the sugar pills but that’s fine. Initially they were a bit irregular but they settled down. Easy to use and remember due to the little packs and stickers they give you. Overall very happy, and can’t say I’ve noticed any side effects. I do already have some symptoms for other health concerns I’m looking into but it’s not made anything worse, and this was pre existing stuff anyway. Might not work for everyone but if you’ve had issues with other contraceptives like me and you don’t want to rely on condoms then I’d give it a go.

I have suspected endometriosis and this has been life-changing for me because it's completely stopped my periods! However, it's also given me spotting after sex and bouts of stubborn thrush. The thrush almost made me quit, but the benefits (no periods or crippling cramps) outweigh the cons. I'm also happy that it hasn't affected my mood at all because previous pills made me extremely depressed.

I have endometriosis and wanted something that would stop my period and ovulation, slynd did this but it also gave me such low blood pressure I was having pins and needles in my extremities, I had crippling anxiety, felt like I was on the edge of a panic attack constantly, intense chest pain to the point I had a full ecg to be sure my heart was ok, I was constipated, I had no sex drive and couldn’t reach orgasm most of the time even alone, I also had irritation and dryness down there and overall it was just awful I wouldn’t wish this pill on anyone. If you have high blood pressure it might help but low is a bad move

Gave Slynd a go as I struggled with headaches and migraines with Cerazette and Cerelle. Slynd has been good in terms of not increasing any headaches which has made a change, however have suffered with breakthrough bleeding constantly since beginning it 5 months ago. It always happens between day 7-day 12 of the pill, never on the placebo pills, which is rather irritating. During this time I am normally hormonal as well, as if leading to my period, so can be very irritable. All in all, an ok pill but just hasn't worked out for me.

This pill has been a game changer! I can’t tolerate estrogen, and I had previously been taking Zelleta which was causing near constant bleeding and my skin looked horrendous. I started taking Slynd in April 2025 and my periods are lighter than without contraception, and my skin has almost completely cleared up. I still get some spots around my period, but that was normal for me before contraception. I haven’t noticed any other side effects 9 months into taking it. My periods were irregular the first 3 months, but now are normal every 4-5 weeks.

This pill made me feel emotionally empty and depressed. I know it wasn't placebo because I'm a pretty anxious person, and have tried everything to get rid of anxiety, without much success! A week on this pill and I had absolutely no anxiety because I had absolutely no emotions. I'm also a very motivated person normally, but I found it really hard to just get out of bed and function. It was wild. Took it for 2 weeks and then stopped, couldn't find any hard evidence that side effects improve after 3 months, and I genuinely didn't have time to be that unproductive and miserable for more than a couple of weeks.

I have suffered with PMDD for years and Slynd has been a game changer for me- my PMDD has vanished completely! I’ve had very few side effects, literally some minor spotting at the start and a very slightly oiler hair. I’d say my sex drive is a little bit lower than before but not a huge difference. My skin is completely normal (other mini pills have given me acne but on Slynd my skin is as nice as always). The biggest positive impact has been on my mental health. I no longer get mood swings (unless I miss a pill) and my periods have completely stopped. I take my pills back to back (I skip the sugar pills) to keep my moods stable across the cycle. It’s such an amazing pill, I hope they will eventually licence this for PMDD so it can help lots of other women (slynd has the same progesterone as the combined pill Yaz which is licenced in the US for PMDD).

I stayed off of contraception for 6 years following bad experiences with desogestrel and the combined pill. I was very very hesitant before taking Slynd and thought about it/researched for months before finally taking it. I have mild PCOS and endometriosis, my periods were completely unmanageable and would stop my life for a week and a half each month and I knew i needed to take action so that I could live a more normal life. My first 4 months on Slynd I had a lot of spotting, the first 2 months i had periods lasting 2 weeks (but farrrr less heavy than usual and no pain) after this time my periods stopped all together. I have previously suffered with acne but have taken roaccutane to get rid of it so I know i am susceptible to bad skin, I would say my skin is slightly worse than it was before taking slyd however, its not bad and it doesn't out weigh the pros of the pill for me. My sex drive is a bit less and I have a very dry throat now and need to constantly drink water (not a bad thing i guess) I have actually lost weight too. I believe this is due to being able to regularly exercise without my hormones/period taking over half of each month and I no longer have the crazy PMS food cravings. I dont think this is a permanent solution to endometriosis at all but it has definitely improved my quality of life drastically and i'm glad I stuck with it and didn't give up in the first 4 months due to the spotting.

I thought I would try this pill because it had some fairly good reviews and I cannot tolerate estrogen. The first week of taking this I had racing thoughts, felt extremely panicky and did not sleep well.. this settled down so I carried on. I strarted spotting a few days before the placebo pills which turned into light bleeding that lasted all the way through to pack 3 !!! It’s a great contraceptive because you can never have sex! My mood has been terrible. I have been tearful, very cranky and irritable at things that would never usually bother me. I have felt quite dizzy at times and almost “unreal.” I have experienced panic like never before. This pill is making me feel like I am going crazy. I’m stopping taking it as I would rather have period pains than feel like this! Awful .
