I've been back on the pill for two months now. My periods have always been regular. I took every pill the first month and skipped my period and missed a couple of pills (at different times) during the second month. I finished my last pill on Sunday and I'm waiting for my period. I've had unprotected sex during this time. I've had the most painful breasts for three weeks now. On Saturday my partner and I had sex and I began to bleed what seemed to be "period blood" during, I put a tampon in afterwards thinking I had got my period but when I went to change it there was just some discharge on it and nothing else. It's now Wednesday and still nothing. I'm sitting at work feeling dizzy and hot and really tired. Not to mention my horrible moods lately, but this could all be pms? I don't think I am pregnant, but is it possible?
