What have I done ahhh

So I chilled with my ex last night and we totally fucked for hours literally, and the whole time he came IN me!!!!!! I'm suppose to get my period in like 5 days and I'm wondering what are my chances of becoming pregnant? I do not take birth control and no we didn't use condoms!!!!! My app says it's a 3% chance! What y'all think?
