I've been on the pill for seven months now, NEVER missed a day until today. I took the last one of the package (the ones you take when you're on your period, I'm on my period right now) yesterday. Then I had unprotected sex that night and today, but he DID NOT finished inside me. Today I realize that I forgot to buy new pills, so I'm missing the first one (after I had sex). That means, pill, sex, no pill that same day. Could I be pregnant?
