Should i be worried? I felt odd pressure in my stomach all yesterday afternoon. This morning i woke up feeling pain in my lower back but it was coming and going now it's about 2 hrs later and it's constant .... noticed my underwear was wet possible amniotic fluid? Im using pantie liners now to see the color of it. What would back labor feel like? I have a doc appointment tomorrow but if anyone has any advice now that would help :) thanks
