I am at home today with rhythmic, painless (mostly) contractions. My midwife suggested lying down and drinking lots of fluids when they started last night. Could this be it? I am trying not to overreact. Yesterday was extremely stressful and I barely ate. Then I walked a lot this morning. So... it could be that. But we shall see.
Later: I just got back from the hospital and have been diagnosed with an "irritable uterus." Go figure. Anyway, that is the deal. Not labor, but also not a good thing. I have been advised to rest all day tomorrow and see what happens.
