My period ended 6 days ago. Today I supposedly ovulation day. This morning I discovered a brown slimy discharge when I wiped, but it later turned into bleeding. My periods are like clockwork, usually so, I'm very confused. I had unprotected sex two days ago and he didn't pull out. I'm not very good at remembering to take my pill either so I forgot to take it that same day. Any suggestions as to what could be happening??
