17 days after my last period, my boyfriend rubbed his penis mainly the shaft aganist, my vagina. it was not inserted at all. i didnt let it go on for long, because i knew the risks of precum causing pregnancy and he did not ejaculate, its been a week now and ive been naseous for about one hour at night two days in a row and today i peed twice in 10 minutes. i am soo worried i am pregnant, my period is due next week . can i be pregnant?
