For me, I went thru 20 hours of early labor with
contractions only and 10 hours of active labor in the
hospital where there have to break my water.
The delivery itself only took 20mins or so.
You are consider in active labor and should go to the hospital if your contractions are 5 mins apart, the pain last more than 1 min each and it's going on for over 1 hour. The 5-1-1 rule.
Unless your water break first then head to the hospital right away.
