Prrgnant question!!!!! ?

So a week ago me and this girl were going to have . She's been on thevpill religiously for two years. Well we ended up not having bc i didn't have a condom. So we were going to try . Well I couldn't fit. I didn't *** the whole night and didn't anything. She started her normal period two days after this. And she just got off. Could she be pregnant????
