Pregnant?

Gr
So twice recently (like in the last two weeks) my boyfriend has gone in without a condom at first, and then put one on before he finished both times. I know pre-cum is still a factor. My period was due today and it didn't come. I'm usually pretty regular. Last month it actually came early. I don't feel like I'm pregnant, but if it doesn't come by tomorrow morning I'll probably test with first morning urine. Just kind of wanting some opinions and reassurance. Thanks
