I need some advice. I'm in my first trimester and it's been difficult  to sleep. I read it's bad to sleep on your stomach. And it's bad to sleep on your back because it stops the blood flow to the baby I'm used to sleeping on my back and in the fetal position. Now when I sleep in fetal position I only get comfy more on my stomach rather than my side.  I tried using my booty pillow to I can lean on it and it gives me space do it's similar to sleeping on my stomach.  Any advice or help?
