How much do you have to dilate to get admitted?
If you are less than 4 cm dilated and your labor isn't active enough for hospital admission, you might be sent home. Don't be discouraged. It is very common to mistake the signs of early labor for active labor.
How far dilated do you have to be to go to the hospital?
The American College of Obstetricians and Gynecologists (ACOG) said active labor for most women does not occur until 5 to 6 cm dilation, according to the association's guidelines.
