pain when I lay on my left?

For the past few weeks, maybe two weeks, whenever I lay on my left my back hurts like there is no tomorrow and all around my belly.

I told my doctor and she said it's just the uterus or my body and everything is squished but I have such a strong feeling this isn't normal.

My back is killing me now from just trying to lay on my left because baby girl is always on the right side and I want her to move around alittle, not constantly be on my right. And she's still breech. At a little over 32weeks.

Has anyone else experienced this? I never had this problem until recently and it worries me.

I hardly ever feel the baby anymore either although I've gotten non stress tests done for the past 2-3 weeks and everything is normal.

But why can't I lay on my left? It's so painful after 5 minutes. I even kneel to try to alleviate the pain.

Could it be something wrong with my intestine? Or something else? This is the worst.
