How long to delivery when 2cm dialated and 100 effaced?

There is no one definitive answer to this question, as the length of labor can vary significantly from woman to woman. However, some general guidelines can be provided.

On average, first-time mothers who are 2cm dilated and 100% effaced can expect to deliver within 6-12 hours. However, for women who have previously given birth, labor may progress more quickly, and they may deliver within 2-6 hours.

Of course, there are always exceptions to the rule. Some women may experience a very rapid labor and deliver within just a few hours, while others may experience a long and protracted labor that lasts for many hours or even days.

Ultimately, the length of labor is determined by a variety of factors, including the woman's overall health, the position of the baby, and the strength of the contractions. If you are concerned about the length of your labor, be sure to speak with your doctor or midwife.
