I've been on birth control for about 2 and a half years. I started taking bc when I met my bf. And I've noticed I have become very moody....somewhat bipolar. I have never been so short tempered and easily irritated before I started taking bc. I go from being really angry to nice. And me and my bf think it may be the bc. Could my bc be giving me too much of a hormone or something? And is there a bc I can take that wont make me like this? And also not get yeast infections. Thanks for any help.
