Fell at 29 weeks, should I go in?

I rolled my ankle stepping off a curb and fell pretty hard on the ground, I twisted to avoid my stomach and landed on my butt, my only injuries were definitely probably sprained or bruised my ankle and big cut on my knee.

Since I didn’t land on my stomach idk if I should go in to get checked or not? Obviously better safe than sorry but I’m alone w my daughter all night so I’d have to go find a babysitter
