Should I stop having sex? Should I be worried ?

Should I just stop having sex? Because I started birth control for the first time one Sunday and that next Sunday I had protected sex, he didn’t cum but I know that if there was a hole in the condom then it’s possible that precum could’ve gone through. I’m only worried because that was during my fertile window (IF IT WASNT EFFECTIVE).. but if the birth control really only takes 7 days to be effective then I should be good right ? I’m on my 2nd week ... ITS JUST SO NERVE WRECKING BECAUSE EVERYONE AROUND ME IS GETTING PREGNANT AND I DONT WANT IT DAMMIT
