I'd do all the stretching and working out. It helps and is good for you. But I also go to the chiropractor. It's helped make it so much more bare able. I'm 38 weeks and still go. It's great!
Stretching, warm bath, tylenol, and when you sit put a pillow behind your lower back to lean back on the extra support can do wonders. I'm 22weeks and my mom has a temperpedic bed with lifting base as I swear I spread all my spare time in her bed it's the only place I can be comfortable
I'm feeling the same I'm 18 weeks my doctor told me just to stretch and try yoga.
