cumming inside of me on the 7 day break?? Could I be pregnant?

chloe
Okay so,my 7 day break from my pill started today and my boyfriend came inside of me whilst having sex. I read that i should still be protected from pregnancy if I've been taking my pill correctly everyday. I've not missed a pill however I've not been taking it at the same time each day. Is there a chance I could become pregnant?? Thanks X
