What worked to relieve sciatic nerve pain in pregnancy for you? Any specific you tube videos or stretches or exercises?

I saw a chiropractor recently for my headaches, and she did some adjustments for my hips as the sciatic pain was just starting, but it's much worse now (not because of the chiropractor, because I'm further in the pregnancy). My core muscles were weak to begin with and clearly pregnancy didn't help that, but it's bad now. Tylenol did take the edge off enough that I could do a few stretches.

(Searching HB for answers brought up my own question about this from last pregnancy. Awesome).
