A membrane sweep can generally be done when a pregnancy is at least 38 to 39 weeks along, most commonly after 39 weeks. The cervix must be partially dilated to perform the sweep. It is usually offered during a cervical exam at prenatal visits around the 39-week mark and can be repeated if labor does not start. This procedure is often done to help naturally induce labor in women who are close to or past their due date. It is a voluntary procedure and your healthcare provider will discuss the benefits and risks with you before performing it. In summary:
- Membrane sweeps are typically done after 38 to 39 weeks of pregnancy.
- The cervix must be somewhat dilated.
- It is a natural way to help start labor without medication.
- It is usually offered during late pregnancy prenatal visits.
- It may cause some mild discomfort and spotting.
This timing and procedure are standard unless there are specific health considerations that contraindicate it.
