Hello everyone, today is my 39th week of pregnancy. My back is very sore, specifically from my shoulders down to my lower back. I can't sleep! I can't find a comfortable position and even a pregnancy pillow isn't helping anymore. Insomnia at night. Could you please tell me about your experiences this week? And could this be a sign of imminent labor?
