Worried

So my bf and I had sex on Nov. 1st. My predicted “ovulation” day was a week later. I am on the pill and have been taking them regularly for the past year and half. We had unprotected sex but he did not finish. I have been having sore boobs for about a week, slight come and go cramping, and I have to use the bathroom more frequent than usual. I am supposed to get my period on the 24th. Should I be worried that I am pregnant?
