Okayy my i had sex with my girlfriend on the 20 of Oct and i didnt use a condom and shes not on birth control. We havent had sex in about 3-4 weeks i never normallyy have sex the day before her period but i pulled out the same way i have been. The next day she didnt get her period its about 1 day late and is this cause her body wasnt use to sex since i stopped 3-4 weeks then it was getting use to it again? i hope shes not pregnant im gonna fie if that happens. PLEASE HEELLLLPPPP!
