Membrane Sweep

If you are overdue, your midwife or doctor may carry out a membrane sweep in order to start your labour. A membrane sweep is the first method of induction that your midwife will try. A membrane sweep may also be referred to as a stretch and sweep.

If this is your first pregnancy, your midwife will perform a membrane sweep during your antenatal appointment at 40 weeks and then again at 41 weeks. If this is your second pregnancy, your midwife may prefer to wait until your 41 week appointment before carrying out a membrane sweep. Many women need two or three membrane sweeps before labour begin and some women may still need further help to kick start labour.

What is a membrane sweep?

A membrane sweep is usually carried out by your midwife during a routine antenatal appointment.  Your midwife will perform an internal examination and will sweep her finger around the neck of your womb (the cervix).  This can sometimes separate the membranes of the amniotic sac from your cervix which in turn releases hormones which may kick-start your labour.

For some women, the midwife will be unable to perform a membrane sweep and instead will try to stretch your massage your cervix. This is known as a stretch and sweep. This action may start your cervix to soften and open, which means that your midwife may be able to carry out a proper membrane sweep at your next appointment.

Does it hurt?

A membrane sweep can be uncomfortable and some women do find it a painful experience. However, this procedure can increase the chances of labour starting within 48 hours and it does not take a long time to complete.

It is important to try and relax whilst your midwife carries out the membrane sweep and you may find it easier if you practise your breathing techniques during the procedure.

The procedure is over very quickly although you may feel uncomfortable or awkward for a short while afterwards. Some women find they have some spotting of blood after a membrane sweep or stretch and sweep is carried, this is normal and your midwife should explain this to you as she carries out the sweep. Some women also experience irregular contractions or Braxton Hicks shortly afterwards.

Is it safe?

As long as the procedure is only carried out by a midwife or doctor, there is no risk to you or your baby. The procedure does not increase the risk of infection to you or your baby and is recommended for all women who are overdue.

Can I refuse a membrane sweep?

A membrane sweep is not compulsory and you have every right to decline one if you are offered it. You could try some natural ways to kick-start your labour at home but if these do not work, you may need to have your labour induced.

If you have any questions or concerns about your pregnancy, labour or having a membrane sweep, you should speak to your midwifeor doctor.
