So yesterday I was at my boyfriends house. At first he didn’t wanna have sex but eventually he did and it was in the shower , I made sure to bring a condom with us but he got carried away. He pulled out before he came all over my ass and all I could do was stand there for a minute just thinking. I made sure to clean myself very good after , making sure nothing got near me down there. I’m supposed to get my period by tomorrow morning or tomorrow night the latest. Is there any possible chance I could be pregnant (btw I am on bc so my period is always on time)
