Nervous

So my bf and I had sex on the 5th and this morning on the 7th. I am on birth control pill and have been for over a year and half. I know you are not supposed to ovulate when on on pill. If I were to ovulate my predicted ovulation day according to this app would be tomorrow. Which means I had a 33% chance of becoming pregnant today. We used a condom and he did not finish. I even checked the condom after to see if there were any holes and there were not. pregnancy on the pill has occurred in my family before. Should I be worried that I am pregnant?
