I've gone my whole pregnancy sleeping on my sides. I was a back sleeper before but switched and haven't had a problem. So tell me why, at almost 38 weeks pregnant, I keep waking up on my back. I was told that if I'm comfortable it's fine, that my body will tell me when to roll over but it doesn't. I don't get dizzy, I don't feel any pressure or weight on me, and my breathing isn't bothered at all. I just feel so terrible, I'm afraid I'm going to hurt my baby :(
