I needed chiro from about 16 weeks with my second pregnancy, due to my pelvis being twisted a bit and things being sore and complain-y second time around.

Really bad back pain, pelvis pain, and right in the groin.

Chiro work and a bit of physio exercises with some regular pool walking helped a lot.

Good luck


ETA: if you're worried about an actual prolapse or anything like that though, I'd be heading straight to the Drs to get checked out.
