So how does that work if you aren't in pain until transition? ;)
With dd#4 I felt like I was in labour for a month. I had a hindwater leak at 36 weeks, after having had contractions on and off since thirty weeks, with no cervical changes. We thought it was all stations go but then there was nothing. I just had constant contractions, with no change, for the next four weeks until dd was born a day after her due date. I didn't even know I was in labour until 5cm. The last two hours were intense but not painful until the last ten minutes or so.
