Should I worry?

My boyfriend and I had sex last night 3 times, 2 times without protection and one w protection

The first time we did it and he said he pulled out in “time” but he’s still worried bc he came but not inside me apparently but he’s still worried

And the other times he pulled out way earlier

And I gotta emphasizes that my period was over the day before and this app says that I have a 7% chance to get pregnant

Soooo.... idk what to do
