Unprotected sex the day before my period!

Dayna
My boyfriend and I usually use protection, however this day we didn't, and he came inside me. It was the second day of my sugar pills (red section) and my period started the next day.
Is there any chance I could be pregnant, even though we didn't have sex in my window of ovulation?
I don't want to wait a whole month to see if I get my next period!
