What Are The Chances Of Pregnancy Having Unprotected Sex On The Second Day Of Menstruation?

Hi i had sex with a girl last night with a condom and found out she was on her 2nd day of her period afterwards. This morning i was attempting to have sex with her again so today would be the third day. She gave me a blow*** for about 15 minutes before we tried putting on a condom. I dont know if i had pre cum or not. Then after the first thrust into her it broke and i pulled out imediatly, would she get pregnet?
