Can a Sweep Bring on Labour?

To carry out a membrane sweep, your midwife or doctor sweeps their finger around your cervix during an internal examination. This action should separate the membranes of the amniotic sac surrounding your baby from your cervix. This separation releases hormones (prostaglandins), which may start your labour.

Can a sweep Bring on labour straight away?

If the membrane sweep is successful you will usually go into labour within 48 hours. Having 2 or even 3 membrane sweeps 48 hours apart is the most successful in encouraging labour to start.

How long after a membrane sweep will I go into labour?

You would expect positive signs of labour within 12 to 48 hours of having a membrane sweep, however. If it takes longer than this, it means the membrane sweep hasn't worked and your body is not yet in labour.
