Hi I Had Sex With My Girlfriend Yesterday, I Didn't

Hi I had sex with my girlfriend yesterday, I didn't ejaculate at all but at one point I stopped penetrating her, and while my penis was outside i heard the condom break (outside of her) so I looked at it and it was broken, as I said I heard a puff of air while it was already out of her, I had urinated twice before this encounter, are my chances of pregnancy high?
