so i had sex with my boyfriend while on my period and when he took the condom off some of the semen landed on the outside of my vagina. we freaked out and went and got plan b 3 hours later. I had slight bleeding a week after i took it. Now I'm 2 days late with my period and I've been Freaking out that it won't come. Ive been having all my normal pre-period symptoms for about a week now but no period. Im just freaking out could i be pregnant?
