As long as its comfortable go for it. I'm 36 weeks and trying to lay on my stomach is like trying to lay on a watermelon
I'm 33+2 and just recently stopped sleeping on my stomach because it would feel sore when I'd wake up. As long as it is comfy to you then it is ok
Im 31+4 and I still sleep on my stomach. More of a side angle lol.
I'm 23+3 and still sleep on my stomach, its the only way I am comfortable
I'm 32 weeks and still sleep on my stomach. It's still comfortable to me.
