I have taken this pill for four months to help with endometriosis symptoms. Previously, I was on Eloine for about a year which worked greatly for me with minor side effects, but changed out of precautions due to having had two or three migraines with an aura. Within the first month of taking Slynd, my headaches became more frequent and intense (to such degree that I need to see a neurologist). Without changing my food habits, I gradually gained 8 kg in the four months of taking Slynd. I also have felt my mental health has been negatively affected by depressive feelings and mood swings. I am a mental health professional and was very surprised at this side effect, given my self-care routines and emotional regulation skills are usually optimal. I also developed adult acne, which I would have been ok with if it was the only side effect. The acne and weight gain have negatively affected my self-esteem. One good thing I experienced on Slynd is that my endometriosis cramps were less intense and that I was able to take this pill continuously, thereby skipping my periods and making endometriosis symptoms more manageable. As a result of this, I had more energy to work out.

I’ve been on Slynd just over three months, and as someone who has tried several other mini pills this one seems to agree with me best. On other mini pills I experienced mild to moderate side effects, notably acne, spotting between periods/constantly and low mood. On Slynd I’ve only had very, very minor spotting and it’s infrequent. I haven’t yet had a period on Slynd but that’s not unusual for me on mini pills. Most notable is my skin, which has seen a noticeable and gradual improvement. Acne has been my biggest challenge on mini pills, with painful cystic acne requiring prescription topical creams for years on end. I’ve just started my fourth month on Slynd and seem to have turned a corner to where I have very little acne, if at all, and no cystic spots. My skin hasn’t been this clear in years! The only other side effects i’ve experienced, but cannot be 100% sure are related, are some moderate thirst in month 2/3 and a strange, weeks-long cramp in the bottom of my foot. I started eating more bananas to try and balance my potassium and the cramp has since gone. Rating 4 stars only because I’ve been on combination pills before (no longer can be on them) and I will always prefer the combination ones over mini pills. But I would say Slynd has been the closest to combination pills I’ve found yet.

The Slynd pill has helped my adenomyosis symptoms! I used to have extremely heavy and painful periods that were so bad that I couldn't walk and leave the house. I had to take high doses of codeine. Apart from a bit of nausea on the first two days (couldve been my period though as I took the pill on the first day of my period) I haven't had any negative side effects.

I had an unpleasant experience using Cerelle. It was the first birth control I tried and wasn't given any other options or choice by the GP at the time. I had a 2month long heavy and painful period, worsened skin, hair loss, severe backne to name a few side effects. Really bad experience for me sadly. Having now tried over 10 other birth control pills- mini and combined, I learned that I am very sensitive to progesterone so the mini pill just isn't for me sadly. I'm now on the Patch and loving it.

I took this for endometriosis, but not worth it because of facial hair growth. I had breakthrough bleeding every 4-6 months for about 4-5 days, fairly light and not too painful. My sex drive and weight were unaffected, however I got thick dark hair on my stomach, inner thighs, chest and face. This destroyed my self esteem so my mood was obviously low. After stopping the hair did not revert back which is common so I had electrolysis which took care of it. Then 2 years later I went back on this pill stupidly to try and help the endometriosis, the hair came back within 2 months. I have since stopped this pill, spent even more money on electrolysis and have had no issues after regarding that. It took about 3-5 months for my cycle to regulate after coming off birth control. I’m thinking about trying slynd as it is supposed to be anti androgenise, we’ll see.

I used this for 6 months hoping my body would adjust but had to stop. My periods became really irregular, and super heavy. The first month, I had 2 periods (both lasted around 10-12 days), second month I got one period, 3rd month I got nothing, and then months 4 - 6 I had 3 periods in 7 weeks, all lasting around 12 days and far heavier than my normal periods. I felt like I had backache most of those last couple of months as that's something that happens whenever I'm menstruating. I've tried other pills and never had side effects like this, so I've stopped these now and will go back to another type of pill.

Had some mood issues during the first 3 months such a depression, low moods, emotional but put that down to my body adjusting. But after 5/6 months all the side effects of depression, low mood, constant crying can back much worse. Had 6 week period cycles with irregular bleeding and spotting and heavy cramping. Had to come off the pills as they were affecting my life so greatly.

Started taking in April 2024 finished the last pack September 2024. Had spotting for the first couple months in the place of period which was frustrating (spotting for 14days instead of normal 5-7day period flow). Once settled, periods just completely stopped which made me feel slightly uneasy as there’s no indicator of “missed period” for pregnancy sirens to ring. Mood was a strange one, felt slightly mentally exhausted but difficult to tell whether that was life or the pill, but I do remember having PMS type symptoms (emotional, cramps) once a month, almost mimicking a period without the bleeds.

I've only been on this pill for two months so there's a chance this may calm down after the full adjustment period, but the side effects have been interesting. Most notably, my cycle has gone from around 35 days to 13 days, and I have been having a period every other week. The first two periods gave me hope because they were significantly lighter - to the point where I was questioning whether or not I should even log it as a period - and painless. However, the next three periods I've had so far have been gradually getting heavier and I'm getting more cramping. It's weird though because, for most of my period it's still quite light, but on around the second or third day, I do have a few hours where it's quite heavy and crampy, then it subsides again and the rest is light. I had spotting between the first three periods but that's stopped now. Other than the annoying cycle changes, I had a constant lingering headache for the first two weeks, I'm getting more acne than usual, and some vaginal dryness before my period. I don't know if this is worth staying on as I'm only on the pill to manage my painful and heavy periods. Current plan is to finish my three months' supply and take it from there.

I'm giving this pill more time because maybe it's just an adjustment. But I've been a bit weepy with sore breasts and spotting every week. Also a really tender feeling in my lower abdomen-especially during sex. Which I hate obviously. So I'm definitely not getting pregnant because I no longer enjoy sex.. so in that respect it is effective. It's getting one more month and then I'm done.
