How long does it take for the cervix to dilate to one finger for delivery?

Patient's question:

The cervix is dilating to one finger. How long does it take to consult about whether it's necessary to be hospitalized now, and if there is any danger at home?

Doctor's answer:

Cervical dilation 1. Latent phase: Regular contractions reappear until cervical dilation reaches 3 cm. On average, it takes 2-3 hours to dilate 1 cm, requiring 8 hours in total, with a maximum of no more than 16 hours.
2. Active phase: Cervical dilation from 3 to 10 cm. Dilation from 3 to 4 cm takes about 1 hour and 30 minutes; dilation from 4 to 9 cm takes about 2 hours; dilation from 9 to 10 cm takes about 30 minutes.
However, the time it takes for cervical dilation varies from person to person. Generally, when dilation reaches 3 cm, you should head to the hospital's labor ward to await delivery! If you're at 1 finger (about 1.5 cm), it's best to go to the hospital when you're truly in labor. During active labor, contractions become more regular, typically occurring every 5-6 minutes with each lasting over 30 seconds.
