birth control
"I started this birth control 6 months ago. In that short span of time I've had THREE yeast infections. I've never had one before and I have no idea what could of caused it other than this birth control. Only other downside is my period cramps are extremely worse than they were before I started the pill. Before it was 3-4 days of regular bleeding, with cramps on the first day. Now it lasts 2 days, barely any bleeding but the most painful cramps I've ever experienced. Whenever those two days come around I have to stay home and normally take pills to sleep through it. That's how painful it is!  Other than that everything else was fine."
