I am 31w 4d and have been experiencing nesting. I literally cannot stop myself from going nonstop cleaning, organizing and getting ready for my baby boy to get here! Today I went way over board with the cleaning, I didnt sit down all day and have not drank as much water as I should. Now I am experiencing contractions, I think. My stomach keeps tightening up and cramping. My back is killing me too. Its happening regularly, about 3 min apart for the past hour. They were getting more painful but now im laying down and seem to feel a little better. Any advice on what I should do? Is this just braxton hicks or possibly preterm labor?
