Me and my girlfriend last saturday had sex for the first time. We used a condom and I pulled out. It was both of our first time having sex ever. She bleed for a few days like spotting and all. We had sex on the 4th and her period was supposed to be on the 6th. It has been a week and still no period. She is very active in sports and a vegetarian. I am really stressing. Is She Pregnant?
