Stressed about pregnancy!

So my boyfriend and I have never had sex and are waiting until marriage. We had a moment about 10 days ago where we decided to do it but after a minute, decided to wait until marriage. It was during the last 2 days of my period and he wore a condom the entire time. He checked a few times during to make sure nothing got out and nothing ever got out. He finished outside of me too. I’m worried about a pregnancy still since it was in even though I was on my period and he wore a condom and never even finished in me. Plus I got some cramps today and my feet feel cold but it’s 14 days until my period so it’s probably just PMS. I’m stressing though.
