I am 37 weeks and 2 days pregnant. I have had a history of preturm labor. This is my forth child and i have never gone this far. I think my mucus plug came out three days ago. I have not had alot of contractions. But i am very hungry and my legs feet and fingers are swollen. And not to be nasty but have a change in color of poop. Im still spotting even a week after my cerivix has been checked. Can all this be a sign that labor os near?including pain n pressure when i walk in my lower abdomen and back?
