I gained weight on slynd when I stopped nursing my baby. I gained weight in areas I normally don't gain weight in despite dieting and intense workouts. Weight is not really coming off despite being off the birth control.

i was on the traditional mini pill for almost a year before switching to slynd. slynd fixed all of the issues I had on the other POP. I did not have breakthrough bleeding, irregular periods or a depressed mood with Slynd. it was a major win-at first. I suddenly noticed I was gaining weight, by month two on slynd I had gained 3-4 pounds, and by the time I quit in month 5 I had gained 11 pounds. 11 pounds in 5 months is insane! I did not change my eating or workouts, so I believe it really was this pill.

I am on Slynd for heavy period and clotting. It stopped the heaviness and clotting. I do have some dryness in my mouth and apparently my vagina. It may have contributed to acne but not sure.

I lost so much hair. I’m done using this. My periods are more painful, I’m so tired now

Really love it! I can skip my periods, don't experience migraines and my acne cleared up!

I gained 30 pounds after starting this birth control. Could not figure out what was going on with my body until I found a reddit thread where other people were experiencing the same.

I’m hoping it gets better. Switched from Errin to Slynd 6 months ago. Hair loss stopped. Acne got better. Those were an immediate win. Month 1 - bled for 1 week. Month 2 - bled for 3 weeks. Month 3 - bled for 2.5 weeks. Month 4 - bled for 2 weeks. Month 5 - bled for 1.5 weeks. Month 6 - bled for 1 week. I naturally have a short cycle, and in the process of trying to force my cycle into a 30 day cadence, I’ve gotten 1-2 days per month of severe headaches before my period (thought my head would blow off without Tylenol) and minor dull headaches for ~1 week before each period. The headaches didn’t happen with Errin - but they are happening with Slynd (and also happened a few year back when I took the combo pill).

It does what it needs to do, pregnancy prevention. Intense emotional fluctuations following the “usual” postpartum journey is definitely a downside
