No. Sleep however you are comfortable. I sleep on my left side, right side and on my back propped up on pillows.

It doesn’t matter. Your body will make you adjust accordingly.

I swap back and forth between sides all night

No

You can sleep on either side, do what’s comfortable

After 30 weeks it is much preferred for the blood supply to baby but prior to that either side is fine

They say it’s the best but you can sleep however you want as long as you’re comfortable. I sometimes wake up on my back and just turn back to the left.

Nope! My doctor said she wouldn’t want me laying on a hard surface on my right side or back for a long time, especially while laboring.
