birth control
"This was the first birth control I was ever on. My mother thought I was on it to clear up my face (I was on it because I had made some bad decisions and scared myself about not being on it). So the doctor put me on this one for acne. A few months later, my face was extremely clear. I didn't like that my period was still heavy and lasted 6-7 days (even though it was regular) though. And after a few months I started to have really strong mood swings. About two weeks into each cycle I would spend up to 6 hours screaming and crying for no reason and then I'd be fine. A month later, it seemed to happen again. I didn't stay on it to see if these swings were coincidental, so I'm still not positive, but since I switched, I haven't had them."
