The first day of my last period was on October 8th (give or take 1 day). I have a 7 day cycle. I normally refill my RX for birth control pills immediately after after it ends, but this month I didn't do so until the 24th. I had intercourse on the 23rd. When I picked up my refill on the 24th I took the entire first week of pills all at once. Afterwards, I continued to take one each day regularly. I figured this is basically the same way Plan B works. Does anyone know how great of a risk there is that I could've gotten pregnant? Any knowledge/info on this matter would be GREATLY appreciated!! Thank you.
