endometriosis
"I've tried this pill twice. Both times, my doctor had to take me off and put me on something else because after 2-3 months, it stops working properly. The first few months are great - very little PMS, 4 day light bleeds, and good sex drive. After 3 months, I dried up, lost interest in sex, and PMS symptoms turned into PMDD symptoms. I started to get migraines, flu-like body aches, 5-6 day heavy bleeds with clots. And if I missed a pill! My period would start within 3 days, even if doubled up to get back on track. Basically, I was having 1 good week out of a whole month."
