Help!!

I was sucking my boyfriend off for a bit and then got on top of him for a little bit, but we started messing around and he trusted inside of me like five times without protection. We stopped after that but I’m afraid of getting pregnant by the pre cum and my fertile window opens in two days, but it says my change of pregnancy is 7% according to the calendar. What should I do. I’m freaking out. What’s the actual chances of me getting pregnant since he didn’t fully cum in me, but I sucked his dick before hand
