Stomach sleeper

Heather
So I am 27 weeks. I have always been a stomach sleeper. I have a sleep disorder so sleep is extremely important. I have a pregnancy pillow I hold to make sure I stay on my side. Seems to work most of the time. Past few morning a I have woken up on my stomach. I am worried I might be squishing her. Or even hurting her. Her movements haven't decreased. Still a little concerned. I am going to try more pillows to hopefully stop me from going on my belly. 
Should I tell my OB?
