How long it lasts: Early labor is unpredictable. For first-time moms, the average length of early labor is six to 12 hours. It's often much shorter for subsequent deliveries. What you can do: Until your contractions increase in frequency and intensity, it's up to you.
For women in spontaneous labor, contractions are usually two to five minutes apart, last from 30 to 60 seconds, and have moderate strength. The easiest way to assess the power of labor is to time the frequency and duration of the contractions (from the beginning of one to the beginning of the next).
