As your baby's birthday gets close, your cervix begins to dilate, or open up. Dilation is checked during a pelvic exam. It is measured in centimeters, from 0 (no dilation) to 10 (full dilation) Typically, if you're four centimeters dilated, you're in the active stage of labor.
There is nothing worse than anticipation when it comes to the arrival of a new baby. New moms are often told they can tell how long they have until the baby is born by the look of the belly button or the drop of the tummy. These signs are not proven to determine when active labor will begin, though they can be an indication that he baby is getting closer to the birth canal.
