help! am i pregnant?

I am sexually active but my bf and I use a condom every single time and I am on the pill. each week of my pills starts on sunday, so my placebo week starts on sunday. I normally don’t get my period until friday and it’s over by monday. how much of a chance is there that i’m pregnant? my bf checks the condom every time to see if it broke and they’ve been fine. but i’m really scared since I didn’t get my period on friday.
