Stomach check if am I pregnant?

Hey so my bf inserted his penis 2-3 times without ejaculating and that happened three weeks from now, I just had my 7 day heavy periods on January 31st-February 6, I know sounds like there’s no chance to be pregnant. But I’m still paranoid. My stomach looked bigger and I am on my fertile days today leading to ovulation and is this just being bloated or I might be pregnant? I tried to push my stomach and I felt some muscles under my belly I got paranoid as fck thinking it might be a baby’s feet but I don’t want to get pregnant plus I’ve been stressed for the past weeks please help me on this. Please.
