birth control ?'s

Maddie
So I just started birth control, I'm on day 9 of the pill. My doctor said my boyfriend and I could have sex unprotected after the 7th day of the pill, I started it the 2nd day of my period... I saw some comments and some people are saying the birth control takes a month to kick in. My boyfriend came inside of me yesterday... am I good or could I be pregnant?
