What are the chances?

Okay ladies last night me and my SO had sex last night he pulled out and ejaculated wiped then 20 min later we had sex again..he didn’t pee after I know some say peeing after flushes out sperm lol just wondering what the chances are of getting pregnant I am in my fertile window..we aren’t actively trying to conceive yet but we aren’t trying to be careful right now either if it happens it happens and we will be so excited! 😍
