birth control
"I've taken this pill for two weeks now and I've had a constant migraine. I just had a baby three months ago so I'm not sure if that has anything to do with it or not. Also had very heavy bleeding for a week then it would stop and start again. Also I'm very moody and sad where I wasn't before I started taking this medicine. If I still have migraines at the end of this pack, I may switch."
