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.

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

Slynd birth control pill  

I was on this pill for about 4-5 months. I’m just going to try to sum this up the best way I can; No change with boobs, no change with weight, acne cleared up, no change with hair growth or loss. Dizziness, several headaches a week. Fatigue, low mood and feeling numb. First 3 months was constant spotting and bleeding with about a week to week and half of nothing in between. Then I stopped taking placebos and zero bleeding or spotting for two months. Also around this time I experienced a huge drop in libido, barely able to get turned on and unable to get wet. The few times I tried to have sex I kept getting a perineal tear in the same spot and this was with a significant amount of lube. Finally found a doctor who told me this was because of my birth control. It impacted my hormones and changed my hormones down there to the point I was unable to have sex. My lips also looked like a prune and were wrinkly. I’ve been off the pill for over a week and my lips are pink, full and plush, and I was able to get wet when kissing my husband which had not happened in months. I feel like I’m coming alive again. Personally done with hormones, we are doing nfp and condoms. I don’t want to scare anyone but this was my experience if you happen to go through the same it may be this pill causing the tearing issue and other sexual function issues (which is listed as a side affect)

Slynd birth control pill  

Some irregular bleeding and headaches in the first few weeks but overall a good experience. This is the first birthcontrol pill that did not give me mood swings and depressive feelings.

Slynd birth control pill  

Chosen due to migraine with aura risk, had hair loss but could be unrelated. I did not bleed for first 3 months, now I do not bleed on the placebo week, but in the third week of a new pack
