Help me out I’m totally buggin’

So, on the 18th, I went over to this guys house and he like fingered me and ate me out but then he went to stick it inside me and I told him no so he pulled away. Then a week later on the 25th I got my period, on the 29th it stopped cold turkey, but now I’m experiencing cramps and I’m very dry down there and it smells quite foul. One of my friends who has children said that it could be pregnancy symptoms. But, I feel like because I got my period that’s very unlikely?? I’m just curious as to how likely it is that I could have gotten pregnant?
