condom broke but i didnt not cum

I had sex with my gf 25 days ago. I only pulled it out since she said she was a bit hurt and I found out that it was broken. I didn't even near cum but there was pre-cum. It was her last period day though, she said her period should be today and there was no period yet. Though she still has a littly stomachache today. Im really worried. is she pregnant?
