I had unprotected sex with my fiancé on the nineteenth of this month right on my firtile window. My period is due in ten days. He did pull out before he came and I'm on no kind of birth control. I've had really light pink discharge but I dismissed at as a little blood from the sex we had. Do you think I could be pregnant? What do you think my chances are?    I would really like to hear your feedback. Please comment!!
