When is a stretch and sweep offered?

Your midwife or doctor may suggest a stretch and sweep when you are close to or past your due date

You may also be offered a stretch and sweep before being induced.

This should be a shared decision, where you make decisions together with your midwife or doctor.

Your healthcare team will explain the procedure to you. You can ask any questions you may have before choosing whether to give your informed consent. You do not have to have a stretch and sweep — it's your choice. You may choose to wait for labour to start on its own.

Who can have a stretch and sweep?

You will not be offered a stretch and sweep if:

• you have a low-lying placenta (placenta praevia)
• your baby is not head down, unless you are planning for a vaginal breech birth
• you have a vaginal infection
• your waters have broken

A stretch and sweep is safe, even if you have had a positive group B streptococcus (GBS) test result.

However, it may not be safe if you have HIV or active .

Your doctor or midwife may recommend another method for the birth if there are concerns for you or your baby's health or safety.

What can I expect during a stretch and sweep?

The procedure is done by a midwife or doctor as part of an internal vaginal exam.

Using gloves and lubricant gel, they will insert their finger into your vagina and check that your cervix is open.

If your cervix is open, they will then be able to sweep their finger around to try to separate the membranes from the wall of your uterus.

If you find the procedure too uncomfortable, you can ask them to stop at any time. If you ask them to stop, they should stop. You should feel safe to advocate for yourself and your clinician should listen to you.

What can I expect after a stretch and sweep?

After the stretch and sweep, you might experience a 'show' — this is a plug of mucus that comes out of your cervix. You might see some blood mixed in with the clear mucus.

You can take and have a warm bath if you are uncomfortable. Always follow the instructions on the packet or speak to your midwife or doctor for advice.

If the stretch and sweep works, you can expect to go into labour within 48 hours.
