Hello! 38 weeks, what symptoms does symphysis pain have, because there's pain in my lower back, but it doesn't bother me much. At 5th month of pregnancy we had strong pains then they passed, now I think I should be worried and go see a doctor or is it normal? Just everywhere you hear about this symphysis problem already starting to believe that maybe I also have such a disease ?
