I have been on one kind of birth control for a while; it’s a generic kind of the kind I was put on. I get my pills for 3 months then I call and get another 3 month supply. Last month I was sent a whole different generic kind, I am on my 2nd month and the first month I was breaking something I haven’t done since I started my pill now my 2nd month I am bleeding like I am on my period and that doesn’t start till next week. And I have never bled like this before. I am sexually active. I have called my doctor but I am waiting for a call back. I want to know could going from one pill to another cause me to do that? Or could I be pregnant?
