Help with sciatica pain

Anyone else dealing with/ dealt with sciatica while pregnant and find anything that helps? I’ve been having a really hard time with laying down, and bending my body in any way. (Getting up from laying or sitting, and bending down) the only way I can lay comfortably in bed is with my right leg bent and pulled up towards my stomach. I’m 17 weeks now, and laying on my belly is starting to get uncomfortable so idk what to do anymore. It’s been getting so much worse recently. I have a doctors appointment in a couple weeks, but I just want relief and to be able to sleep at the very least 😢
