If you find yourself past your due date, you might encounter the term “pregnancy sweep” or “membrane sweep.” Contrary to its name, it’s not a cleaning ritual involving brooms but rather a gentle procedure aimed at kickstarting labour. Let’s delve into what exactly a pregnancy sweep entails and what to anticipate during the process.

What is a Pregnancy Sweep?

A pregnancy sweep, also termed a “membrane sweep” or “stretch and sweep,” involves an Obstetrician or Midwife attempting to separate the membranes of the amniotic sac from the cervix. This action triggers the release of labour-inducing hormones, thereby thinning the cervix and encouraging childbirth. The “stretch” component involves the gentle widening of the cervix using two fingers. However, this procedure won’t be performed if your cervix isn’t ready for dilation.

Why Might You Need a Pregnancy Sweep?

If you’re beyond 41 or 42 weeks of pregnancy with no signs of labour, your Obstetrician or Midwife might recommend a sweep as a natural method to initiate labour before considering induction, which involves artificial hormones. Remember, full-term pregnancy spans from 37 to 42 weeks, so waiting beyond your due date is not uncommon.

What Does a Pregnancy Sweep Involve?

The procedure entails a vaginal examination where the Obstetrician or Midwife uses their fingers internally to “sweep” around the edge of the membranes. It’s a brief process typically lasting seconds. If they can’t reach the amniotic sac, they might attempt to stretch and massage the cervix to prepare for a future sweep.

Is a Sweep Equivalent to Induction?

A pregnancy sweep is often offered as a precursor to induction as it can effectively kickstart labour without the need for artificial hormones. If labour doesn’t commence, additional sweeps might be suggested, or induction options could be discussed.

How Painful Is a Sweep?

While discomfort is common during the procedure, it’s typically not intensely painful. Keeping in mind the purpose of the sweep can help manage any discomfort, especially if you’re eager to meet your baby.

How Effective Is a Pregnancy Sweep?

Research suggests that most women undergoing membrane sweeping enter spontaneous labour, often within 48 hours of the procedure. The success of a sweep can vary, but its aim is to initiate labour within this timeframe.

What Happens If It Works?

If you experience period-like pains within 48 hours of the sweep, it’s likely that labour has commenced. If not, additional sweeps may be considered before discussing induction.

Final Tips

Wearing a sanitary towel is advisable as light bleeding may occur. However, it’s rare for waters to break during a sweep. Ultimately, a pregnancy sweep brings you closer to meeting your little one, a moment you’ve eagerly anticipated throughout your nine-month journey.
