Pregnant?

So lost my virginity on the 31 of may, we used protection and he didn't come outside of me, he even checked to see if the condom broke but no it was fine. Then I was late by 3 days for my period but when it did came it was on the 28 of June but it was light and as the week progressed it got heavier, so now my period was due 5 days ago sooo idk what to think.
