HELP! RAW CHANCES??

Hi so I just came back from my this guy's house and we didn't really do anything but I gave him head and he fingered me but not for a long time. SOO he wanted to have sex but of course I said not unless you have a condom and he didn't but he slipped it in a raw 4 times but he was dry and then I stopped him. It was a good 50sec I would say and then I gave him head. He never finished because I had to go, we really didn't have sex just slipped it in a little of time but that's that but I just checked my app and it says I have a 7% of getting pregnant today and I'm so scared I have a chance because of what just happened. HELP  ( my fertile window starts in 3 days.
