Ok so i have never been on birth control and last saturday(Sept 17th) i started on the pill. I was told at planned parenthood that for the first week to use a condom and then after i should be fine. I have been taking the pill as directed at the same time each day, except yesterday i took it a couple hours later then usual. Well anyways, my Fiance and i had intercourse and usually if he doesnt wear a condom he pulls out, but last night he didn't. So my question is: Is there still a possibility i could end up prego? And should i take a plan B just in case? Anything will be much help, thanks in advance!
