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.
Assuming your pregnancy is full-term, though, time will tell: If you're in early labor, your contractions will gradually become longer, stronger, and closer together. Eventually they'll be coming every five minutes and lasting 40 to 60 seconds each as you reach the end of early labor.
