Falling during pregnancy

Hi mommas so this is my second pregnancy, I have been much clumsier then my first (not by choice) I’ve slipped at 33 weeks pregnancy took a hard fall but to my butt I went it to l&d baby was fine so I was just left with some sore pains to my back. Fast forward to last night I slipped yet again this time it was getting out the shower I landed with one leg in the tub the other out and my butt on the tub it hurt some nothing to bad I kept a close eye on baby she’s been moving but the pain has grown. My pelvic area and lower back hurt. Should I be concerned? I am now 37 weeks pregnant btw
