Bishop Score Calculator

The Bishop Score is a clinical tool that assesses the likelihood of successful vaginal delivery by evaluating cervical dilation, effacement, station, cervix position, and fetal membrane status.

To calculate your Bishop Score, add up the scores for cervical dilation (0-10 cm), effacement (0-10%), station of the presenting part (-3 to +4), position of the cervix (anterior or posterior), and fetal membrane status (intact or ruptured).

Cervical dilation measures how open your cervix is in centimeters, effacement measures how thinned out your cervix is as a percentage, station indicates where the baby’s head is relative to the pelvic floor, cervix position refers to its orientation (anterior or posterior), and fetal membrane status checks if the amniotic sac has ruptured.

A higher Bishop Score indicates a better chance of successful vaginal delivery. Scores typically range from 0 to 18, with scores above 8 generally considered favorable for spontaneous labor.

Yes, you can still calculate your Bishop Score even if your membranes have ruptured. The membrane status component would simply be scored as 0 instead of -3.

Your healthcare provider may recommend recalculating your Bishop Score periodically, especially as you approach the end of pregnancy or if labor has not begun. This helps assess changes in cervical readiness for delivery.

A low Bishop Score can be influenced by various factors such as inadequate uterine contractions, insufficient fetal descent, unfavorable cervix position, or incomplete effacement. Your healthcare provider may recommend interventions to improve cervical readiness.
