Back hurts way too much!

Arelie • Mother of one lovely daughter of a 2 year old and son 7 months old.
I'm due May 4th and my back is killing me soo bad. I told my doctor about my constant pain and all she said was that it's normal. I'm 4'11 and my belly is way bigger than my first pregnancy. So I feel like I'm carrying way too much belly weight. Is anyone else feeling this way? I can barely walk or stand for too long before I feel like dying. Also in bed I can't get comfortable at all!! I can't breathe or roll over to switch sides. My arms and legs fall asleep a lot. 😭 I'm sorry but being pregnant hasn't been fun for me at all. What do you women do for the pain? What works best to relieve it?
