Likelihood is a bit tricky to determine here tbh, it depends on a whole host of factors. The general understanding is that it is about a 3% likelihood of conception - that largely does not account for much in the way of age differences and other factors. (So in this case it could be much higher or even lower)
Seconding the don't have a kid thing though, they always do it ╥﹏╥ and the kids appearance will no doubt defy basic genetics. Bonus points it they have twins.
Pls don't be a foreshadowing...
I don't like this trope where they get pregnant on their first time. Like, for one, that's highly unlikely, and two, let them enjoy their relationship before having a kid goddamit!
