What are the chances

I had sex on my ovulation day (May 23rd) with a condom on. I didn’t feel any leakage or anything. In fact I’m not even sure he finished..that’s how I know I didn’t feel anything. We both have had sex before and used condoms so I know he knew how to use one..all I wanna know is what is the chance of getting pregnant if your ovulating and used a condom.
