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.
These contractions can feel like menstrual cramps or like a lower backache that comes and goes. During early labor they might be as far apart as 20 to 30 minutes. Over the course of time, your contractions are likely to begin occurring at shorter intervals of perhaps every 10-15 minutes or less. When your contractions are consistently 5 minutes apart, it is time to call your health care provider.
