Who has been in this situation? I have a 28 day cycle. I had unprotected sex on day 8th and he came inside me. I had another unprotected sex on day 13th but he pulled out before coming. To be doubly protected i took postinor(emergency pill) about 10hours afterwards. To my utmost surprise I'm 3days late and got a BFP. I'm surprised at it all and dont know the particular act that knocked me up
