I had started my last period on the 2nd of November and lasted until the 6th. It was my first 'real' period since coming off of the pill in October. I had unprotected sex with my boyfriend on the 8th and 10th. Also, he stuck his penis in me the day before ovulation, the 16th, so I picked up Next Choice. Since then I have been using my diaphragm with spermicide and the withdrawal method. My period should be due on the 29th. So do you rhink it is likely that I am pregnant?
