absolutely agree, i slept left or right before 30 wks, now i sometimes sleep with face upwards ar (though when i turned back to right or left, it was actually very tired when face upwards)
I've been forcing myself to sleep sideways since I know I'm pregnant cos I'm a back sleeper. But alot of times when I wake up, I found myself sleeping on my back.....I guess I'm so used to that position. I need to work much harder. hehe
