ovarian cysts
"I started this birth control to help with my PCOS and crazy periods. My periods were always 8-10 days and pretty heavy. But I started my period just 10 days into this medicine and it continued for 19 days. I've never had a period that long. My depression was made worse, my sex drive was gone, dizziness, ridiculous mood swings, never wanted to eat, the list just goes on. I never had this issue with the previous two birth control pills I used 7 years ago. Needless to say, I stopped this medicine and will not be taking it again. I'd rather deal with a horrible 9 day period, than a horrible 19 day period."
