Why shouldn't pregnant women sleep on their back?

Question

Doctors have told me not to and I've read it. But why not? I wake up in the middle of the night on my back

Answer

Your body will tell you when you can't anymore. When you sleep on your back when your belly is bigger it can cut off the blood flow of a large artery in your back causing you to become light headed, cut off the circulating in your arms, and prevent blood flow to the baby which will usually make you feel sick to your stomach.

Answer

I slept on my back through most of my first pregnancy (until it was uncomfortable) and am still doing it this time around, currently at 6 months. 
As someone else said, your body will let you know..

Answer

From What To Expect
“The back sleep position rests the entire weight of the growing uterus and baby on your back, your intestines and your vena cava, the main vein that carries blood back to the heart from your lower body”

Answer

I slept on my back all the time and I have a healthy 7 month old. I don’t know why but it didn’t seem to bother us.
