Am 18 and my girlfriend is 16. We had sex for the first time day before yesterday whike she was on her period. I used a condom to start with after I ejaculated I threw the condomaway and later mated again wwithout peeing or wahsing my penis.. I repeat she was on her periods and it was her 4th day. So nothing has happened except her vagina was burning and hurting a lot an hour after we were done and it gradually decresed and she didn't bleed the next day. While the second time I didn't ejaculate Inside rather I pulled out and ejaculated outside. Is there any chance of her getting pregnant?
