I ve had sex with a guy six days ago and I was supposed to have my period two days after. It s been four days now that I haven t had my period yet. I usually never miss a period. We were using a condom at the beginning, but then he took it off, he didn t ejaculate inside me, but what about his pre-cum? Is it possible that i might be pregnant even though it was two days before my period due? Or is my period just late because it was my first time having sex?
