Hello Mommies and Would be Mommies.. I am in my 8th month of pregnancy. I have heard people asking to sleep only on the left side. However due to pain cz of continuous sleep at one side, I develop a restless feeling and turn to the right side. Is it fine or is that going to affect the baby? Please please let me know. Little worried on this part.
