Birth Control

Ever since I started my birth control, I've felt weird. I feel like I'm not the same person. I looked up side affects for my specific type of birth control but there was nothing on there about mood swings. I'm on it because I'm in a healthy sexual relationship with my boyfriend of a year. We don't want to become pregnant. I don't wanna stop taking it becuase of that. But then again, it's making me feel not like me.
