I am on birth control for Ovarian Cysts, and I have been taking my pill everyday, around the same time everyday also. . I switched to a different birth control because they ran out of the one I was on at the pharmacy. It seem like ever since I stated taking that birth control things haven't been normal. Like for about 3 to 2 weeks now, I have had been bleeding everyday. Sometimes it light and sometime it's heavy.

What could this be? Should I go see my OB GYN doctor?
