how early can effacement occur before delivery
Itâs generally estimated that the cervix will dilate one centimeter during each hour of labor, but this cannot be generalized for every woman or every pregnancy. 0-4 centimeters dilation is considered early labor, and itâs not uncommon for a woman to be up to 2 centimeters dilated several weeks before giving birth. Dilation of 4-7 centimeters occurs during active labor. 7-10 centimeters is the transition phase (shift from active labor to the final phase, delivery), and when your cervix is at 10 centimeters (about the size of a newbornâs head), itâs considered fully dilated and youâre ready to give birth.
