so i’m on my period and me and my boyfriend did anal. we’re both 19. he came on my butt and it dripped down and it’s all over my tampon string and that area. could i be pregnant? i’m also on birth control but i’m worried because birth control didn’t work on my mom. that’s how my little brother got here. we don’t know if it’s because another medication she’s taking messed it up or if it just didn’t work. so could i possibly be pregnant?

edit : don’t comment unless you have an actual answer. scroll on and continue with your day. thank you to the people that gave actual answers instead of laughing at me.
