For the baby to pass into the birth canal, the cervix must be ten centimeters, or about four inches, open. In early labor, contractions are irregular and mild. It is safe to be at home during this time, unless your healthcare provider has given you other instructions. Walk around, eat lightly, and drink plenty of fluids. Early labor begins the work of thinning and opening the cervix.
Active labor means that contractions are regular and strong.
Contractions are regular when they occur every three to five minutes like clockwork. You will know your contractions are strong when you cannot talk through them. Active labor opens your cervix all the way to ten centimeters. Some women have natural childbirth, using no pain medication. Others may need pain relief.
