2. What does a membrane sweep consist of?

Your physician or midwife will try to insert a finger into the entrance of your cervix, between the amniotic membranes and the uterus. Then, gently but in a firm way, he will move the finger in a circular way trying to separate these two structures. If done correctly, this technique will release prostaglandins, which are the hormones capable of start the labour process.

3. Does a membrane sweep always kick-start labour?

A membrane sweep should increase the chances that labour will start in the next 48 hours. If your cervix is already developing the changes associated with oncoming labour (softening and dilation), the chances become higher. The outcome of this technique may vary from woman to woman, needing just one or more than one sweep, or passing directly to induction methods.

5. Is a membrane sweep obligatory?

No, it is not in most places. If you want to and as long is it safe, you can refuse to have a membrane sweep and wait for the labour to start naturally or go straight to induction. It is normally your choice. Either way, talk to your physician or midwife for recommendations.
