I am on my 2nd pack of birth control. 2 weeks before the week I am supposed to have my period, I started having what I would describe as heavy spotting or a light period. I could leave a tampon in for the whole day and not use it up. Anyways, my boyfriend and I have unprotected sex sense I am on birth control. I missed my period this month. Is it possible that I am pregnant? Or did I just have my period early (the 2 weeks of spotting)?
