Sleeping position!

Hi ladies! I am 30 weeks 4days. It’s been getting pretty uncomfortable for me to sleep. I try to only sleep on my left side because that’s what everyone says I should do. I asked my OB about that and he told me I can sleep however I feel comfortable, either side & if I wake up flat on my back not to be scared , that it’s ok. What do you all think or what position do you all sleep in? Oh and I also have about 5 big pillows all around plus my body pillow lol
