What are the chances of getting pregnant if i have sex a day before ovulation but i am on birth control for a month now and he used a condom?

Pregnant?: If you think you might be pregnant wait until you have missed a period, get a home urine test kit and check a first AM voided specimen. It is very unlikely for you to be pregnant if he was wearing a condom which remained intact and there was no leakage around the condom. Now if he put it on after penetrating you first, that might be an issue. Good luck

If: Condom intact. Rare that you will get pregnant. Esp on birth control as well. So percentages on your side
