So two weeks ago I started my period, and it was my birthday the next day so I took 3 birth control pills to stop it (I wasn't taking them regularly at the time, I had some left over from last year). It stopped for a few days then started again and lasted 10 more days (they are normally around 7 days long). The 10 days finished on last Wednesday/ Thursday. I had sex two days ago (Sunday) without protection and I was wondering what the chances were of me being pregnant? I know no one will know for sure but I'm not sure if I was ovulating at the weekend, which I know will increase my chances of becoming pregnant.
