I ended up going in after midnight. My contractions were 2 min apart for awhile. Then they went crazy and we're 4 min long! I was only 1cm and thick. (Which I was told at 33 weeks I was soft, and at my 39 wk appt last thurs I was told I was thinned).
So at 330am I was still only 1 cm so I decided to go home to try and sleep. Took tylenol pm and now they seemed to stop! But I slept. I did lose my mucus plug too, so I hope that helps progress things...
I would still go to hospital! That's a long time to be having contractions!!! Baby may come while you're at home!
