Im 39 weeks pregnant and 2cm dialated baby is engaged head down how long do you have?

There is no way to give a definite answer to that question, given that the amount of time from dilation to delivery can vary widely from woman to woman. However, since you are already at 2 cm dilated and the baby is engaged head down, you could potentially be in labor within the next few days or even hours.

Some factors that could influence how long it takes you to deliver include:

* The size and position of your baby. A smaller baby and/or a baby who is in an ideal position for delivery (head down, facing your back) may come more quickly than a larger baby or a baby who is in a less favorable position.

* Your age and health. Younger mothers tend to deliver more quickly than older mothers, and women who are healthy and well-rested tend to deliver more quickly than those who are not.

* Your labor history. If you have already had children, you may dilate more quickly and have a shorter labor than you did with your first child.

It is important to remember that labor can progress at different rates for different women. If you are concerned about the length of your labor, talk to your doctor or midwife.
