Will she get pregnant?

my girl friends period ended 2 days ago and last night we were having and the condom snapped and i pulled out right away. shes experienced and said its ok cuz she had her period 2 days ago and she said she doest start ovulating until the middle of the month and all this stuff....she said it will be ok because she knows her cycle. it was my first time so im nervous....i didnt bust in the condom either. wat are the odds of her getting pregnant?
