When should my period come on Gildess?

This is my first time taking birth control and my first month on Gildess. I'm currently in the middle of the gap week and wondering when my period should start. (My gap week started on Thursday.)

I did have sex a few times this week (finally got to see my boyfriend! Long distance sucks...) but he never came inside me. I couldn't be pregnant, right?

I never missed a day taking the pill and was only a few hours late taking it a few times during the month.

Things have been a little nutty lately because I move back in for college tomorrow. Maybe that's contributing?

Any advice is greatly appreciated!!!

TL;DR When should I expect my period to start during the gap week?
