I'm having the same problem all the time.. I'm 26+5 weeks pregnant and I have sharp pains in my back and I can't breathe even when my back stops hurting...
I had the same problem earlier. I think its because I ate to much. It helps to sit up, arms above your head then switch to doggy style position, and try pelvic tilts.
A fan on the face definitely helps
I'm 32 weeks and I have the same problem on top of that I have heartburn.try and prop up your pillow under your head and maybe lay on your left side and put a fan in front of you to help you with air circulation. that's whatI do and it helps.
Pillow between the legs? Idk I have same problem
... obviously lol but I always have a fan on me too.
