About the same as any other woman trying to get pregnant. A healthy couple, I believe, has a 25% chance of becoming pregnant every month.

If you do not wish to become pregnant, get on birth control.

Thank you for answering my question, we are just letting it happen if it happens... I was just wondering the possibility of getting pregnant since he went inside me twice... Towards the end of my period. People have been saying you have no chance... If you have your period.
