Baby S is only a few months away

So I'm pretty concerned. I've been diagnosed with round ligament pain since 20 weeks and I'm now almost 29 weeks and it's only gotten worse since the diagnosis. I have a tilted uterus which means Lorelai (baby S) is sitting on my tailbone most of the time and that is a literal crippling pain. I have to stop what I'm doing and just be on hands and knees letting my belly hang above the floor till my tailbone is relieved. I don't know what to do about it because with one comes the other it's like thunder and lightning. The doctor says I'm measuring 2 weeks behind now so they are concerned the baby is not doing well.
