With my first, my water broke, so all my contractions happened in the hospital with pitocin. With my second, all my contractions happened over one day and night, but I thought I was having gas pains and constipated. I had no other Braxton Hicks contractions leading up to that day. With this one, I have been having Braxton Hicks contractions since last night, and I am now 1-2 cm dilated, and they don't feel the same as my contractions last time.
