The condom broke!!

So Thursday night me and my boyfriend were having sex when he pulled out and was just sitting I was pretty sure he hadn't finished when he said look and the condom had a big hole in the top. He said he didn't think he had came. But you wouldn't of been to tell due to the hole. He has never came that close to cumming inside me ever. I am on birth control but I'm not always the best at taking it right on time due to many reasons. My period is due tomorrow. I'm just really scared. Could I be pregnant?
