During labor, the cervix undergoes dilation to allow for the passage of the baby from the uterus to the birth canal. This process occurs in stages, starting with early labor when the cervix dilates from 0 to 3 cm, progressing to active labor with dilation from 4 to 7 cm, and culminating in the transition phase where dilation reaches 8 to 10 cm. #laboranddelivery #givingbirth #pregnant #whattoexpectwhenyoureexpecting #firstpregnancy | Labor & Delivery
