When he cums inside

Bianca

So... normally I use bc and a condom to be extra careful. Yesterday we decided to do without a condom (still using bc tho). I got my period today which is a week early but I have felt it coming for days.

My question is, if it did happen that I got pregnant, would I still have this period because it was coming before he came inside me? Should I wait a couple weeks to see if I get my next period?
