Could I be pregnant?

So my boyfriend and I had sex on the 7th of March and my period was supposed to come two days ago. I have just switched birth controls from one pill to a different one I was half way through my second pack when we had sex we also used a Condom. His dick was touching around my vagina before he put the condom on and was a little wet with precum. As I said I’m two days late what are the chances I’m pregnant?
