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.
How can I tell the difference between true labor and false labor? Usually, false labor contractions are less regular and not as strong as true labor. Sometimes the only way to tell the difference is by having a vaginal exam to look for changes in your cervix that signal the onset of labor. One good way to tell the difference is to time the contractions.
