I took plan b during my first week of active birth control pills because this guy I was having sex with ejaculated in me 3 times that night. Please don't lecture, I now know that I probably didn't even need it but I was just scared. I've been reading and people say it can delay your period. Will that be true for me? I had just got off my period two days before I took plan b so is it possible that I will actually get my period this month? Or will it get delayed a week or until the next month?
