This may be the incorrect format or place for such a question but here this goes.

My condom broke during intercourse with my girlfriend the day her period bleeding had stopped. Immediately after I went and bought two doses of Plan B. One of the doses was taken ~20 minutes after intercourse, and the second was taken ~12 hours after intercourse. My question is this: what are the odds of her being pregnant?

Most of my research has shown that she is not likely to be, but I would like a more educated answer.

Thank you so much for your help.

Also, it has been less than 5 days since this incident occured, would it be advisable to purchase the Ellaone pill aswell?
