This morning I woke up completely tired as if I didn't sleep last night. I read online that a lot of women don't get that burst of energy. I'm not sure if it's anything or if it's nothing but about 20 minutes ago I had this very sharp intense pain in my lower back also in my pelvic area it was so intense it felt like as if the baby was moving even lower and going into place I could feel her kicking in my side it feels like she super low now. Could this be a sign of labor starting? I am 37 weeks and three days.
