Ook..thankyou ..

It's always better to sleep on your side. Preferably left side.

Hi first trimester is fine but you are 5 months pregnant so better to sleep on left side. If you want you can change sides.

Experts recommend pregnant women avoid sleeping on their backs during the second and third trimesters. 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.
