The first stage of labor is the longest and involves three phases: 1  Early Labor Phase âThe time of the onset of labor until the cervix is dilated to 3 cm. 2  Active Labor Phase â Continues from 3 cm. until the cervix is dilated to 7 cm.  Transition Phase â Continues from 7 cm. until the cervix is fully dilated to 10 cm.
A baby is usually born about 38 weeks after conception. Although the cervix gradually softens and effaces (decreases in length) as the baby grows bigger in the uterus, it does not open or dilate until you are ready to give birth. If your cervix is short before the 37th week, you may go into preterm labor.
