Okay so my girlfriends period started on the 6th October and lasted a week.. We then had sex on the 16th, with a condom and with me pulling out before ejaculation (I know this is overkill but I'd rather be safe than sorry..) my girlfriend then got a period like discharge of blood yesterday, as well as today. Is it possible that she is pregnant?? Ps: we where both virgins before the 16th. Thanks for any help you can give me!Pps: She was waiting for her next period before beginning to go on the pill. We however had a few days booked away for the purpose of our first time..
