Constant poop feeling

I’m 32 weeks 3 days and yesterday evening I bent over (no more than 6–12 inches at most) and felt a sudden sharp pain through my pelvic region. It didn’t feel anything like round ligament pain which I’ve had a ton of. I immediately noticed pressure afterward. It wasn’t strong & I was busy so i don’t know how long I had it or if it was coming/going. I’ve now had a constant feeling that I have to poop. Think it’s a sign my baby already started to drop? I’m a FTM so this is all new to me!
