Pelvic pain.

Pregnant with my 2nd and had a lot of pelvic pain in the 3rd trimester with my first but it hit around the 2nd trimester this with my second. So I've already been feeling pretty weak and today I slipped on wet floor at work and did like barely the half splits and my pelvis feels destroyed. I can hardly take a step after going from sitting to standing, I just don't know what to do about it, I thought maybe a chiropractor could help but I don't know. Just looking for tips or advice.
