My boyfriend and had oral sex. I gave him a blowjob and ha****b and he cummed into a piece of cloth (not on me). I wiped the cum off his penis. We waited about 10 minutes later, until he started to rub his penis against my vagina (not inside). Im scared that some of his old cum might of went inside my vagina. I took Plan B less than 2 days later, and Im not sure if it worked. Am I pregnant?! Or do I have a high risk of pregnancy?! Please Answer!
