I've been on Yaz for about 7 months, i haven't missed a pill in the last 7 days, i had unprotected sex last night, took a pink pill this morning, will take another pink pill tomorrow morning, however the day after i'm supposed to start the white inactive pills. Could i possibly get pregnant if i take a white pill less than 72 hours after unprotected sex? I've been told that sperm can live in the vagina/uterus area for up to 72 hours, i really don't want to skip my period this month, but i also do not want to risk getting pregnant... help?
