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.
Labor Contractions Are Strong, Repetitive, and Persistent. You can time them. When contractions are five to seven minutes apart for at least an hour, with each one just as intense as the last, you're in labor, says Myron Bethel, MD, chief of staff at Good Samaritan Hospital in Los Angeles.
