I've been taking the pills for about 3 years. I don't think that they are th reason for it. But, in the last month I have been taking them pretty good, BUT last month (before my 1st weird period) i hadn't been taking them like I should. I've been bloaded, crampy (weird twinges in abdomen), headaches, trouble sleeping, acne, really tired. Could I be pregnant and still be having my period because of BCP?
