Back pain 😫 any advice?

Right now I'm in my 3rd trimester and this pain has only been here since my 2nd trimester, so I'm positive that the reason is due to pregnancy...

It's a sharp pain located in the lower left hip/pelvis area(??) It goes away when I sleep. But after working as a server on my feet for hours, I'm basically limping to bed every single night...

It's in a spot that I cannot crack too which is so frustrating, I've had my SO step on it, I've gone to the chiropractor (they won't do anything until you pay for a huge monthly plan ..), and I've tried yoga.

Any of you ladies experiencing a similar pain? I would love to know what I can do to fix this, and I'm open to ANY suggestions 🙏🏻😭❤
