My ex boyfriend and i had sex yesterday unprotected. He didnt come inside of me but when he pulled out it was all over my vagina. Ive asked a few people and looked on the internet to see if anyone canhelp. Ive heard things like: sperm swims so i could be, sperm dies as soon as it hits air, and that you actually have to have his cum inside of you directly.. Ive been told to take a pregnancy test this weekend to see what it says. Is there any possibility that i could be regnant?
