Awww... that's no good mama! I hope you can find someway to be comfy.
I have back issues to also. I hurt my lower back while in training for the Army, so it hurts pretty much every single day regardless. Now that I'm pregnant it's getting worse. I know that it can really only get worse from here too, which sucks. The worst thing in my book is round ligament pains though. They are kicking my butt.
