What are the odds of my girlfriend becoming pregnant?

“Me and my girl friend were having sex and the condom broke. Right when it broke i pulled out. Her period last started on the 15. The day we had sex on was the 12 of august. what are the odds of her getting pregnant. Someone told me that her ovulation was supposed to be august 1st and it could range from 25 of july and the 8th of august. so what are the odds of her becomming pregnant.”

A: “A woman typically ovulates 14 days before the start of her period. Since your girlfriend started her period after the condom broke, she is not pregnant. In the future, always remember to correctly use protection every time you have sex or contact a reproductive health care provider about starting a more effective hormonal method of birth control.”
