Slynd birth control pill  

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.

Slynd birth control pill  

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).

Slynd birth control pill  

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

Errin birth control pill  

It has improved my period pain a lot but it’s made me extremely irritable and moody and depressed and I’ve been experiencing frequent headaches for 2 months. I am planning to switch off of it for the sake of my mental health.
