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.
One contraction may be 15 minutes apart from the next or as close as 5 minutes. The length of the contraction is probably 30 seconds to one minute in length. As the first stage of labor progresses, your contractions get closer and more regular.
