Can some please give me tips on how to sleep or reduce my pain?

I have a L5-S1 central herniated with annular tear 1.5 by 4 mm indenting epidural fat. 3 cm tarlov cyst in the sacral canal extending into the right neural foramen at S1-S2. It been making my sciatica nerve hurt. It’s been very painful and I’ve only been able to sleep on my back. I am going into my second trimester next week and I need help/tips on how to avoid laying on my back. I will appreciate any advice. Thank you.
