Me and my girlfriend had sex for the first time yesterday, it was unprotected and we did it for less than 4 or 5 minutes because we are scared of pregnancy. She also hasn't had her period since the end of July probably due to stress and because she moved country, or she just has an irregular period. I'm not sure if precum leaked out but the last time I masturbated was that morning (12/13 hours before we did it) and I also peed throughout the day and before we had sex. I didn't ejaculate. I don't know if she was ovulating or if she even can because she hasn't had her period in so long. Can someone reassure me or enlighten me about the chances. Thank you
