How do I know when labor is near? I already lost my mucus plug, I was told a week and a half ago that I was 60% effaced I have already dropped, I have constant menstrual like cramps , I feel soo much pressure, I am getting mildly nauseated,and feel a sharp like pain In my abdomen as if my daughter is laying on a nerve. ,and recently heard like a bone popped in my vaginal area.
