Cervical Cerclage Complete

Cervical cerclage (stitch) in pregnancy — what it is, when it's used, and recovery.

A cervical cerclage, often just called "the stitch," is a small procedure used to support a weakened cervix during pregnancy. It's usually offered to women who have a history of late miscarriage or premature birth linked to the cervix opening too early, or where scans show the cervix shortening. Being told you need one can feel worrying, so here's what actually happens, when it's used, and what recovery looks like.

What a cervical cerclage is

  • A cerclage is a stitch (or sometimes a band) placed around the cervix to help hold it closed until later in pregnancy.
  • It's typically recommended for cervical insufficiency (also called cervical weakness), where the cervix starts to open or shorten without contractions.
  • The aim is to reduce the risk of late miscarriage or very premature birth by giving the cervix extra mechanical support.
  • Not everyone with a short cervix needs one — your obstetric team will weigh up your history, scan findings, and individual risk factors before recommending it.

When it's used

There are generally two routes into having a cerclage:

  • Planned (elective) cerclage — usually placed around 12–14 weeks, offered to women with a known history of cervical weakness, previous late miscarriage, or prior cerclage in an earlier pregnancy.
  • Emergency (rescue) cerclage — placed later, often after a scan or examination shows the cervix is already shortening or the membranes are visible, sometimes up to around 24 weeks. This is a more urgent situation and is assessed carefully by the team, as not everyone is a suitable candidate at this stage.
  • Ultrasound-indicated cerclage — offered to women with certain risk factors who are having regular cervical length scans, if the cervix is found to be shortening during the second trimester.

Your consultant will explain which category applies to you and why, since the approach and urgency differ quite a bit between planned and emergency procedures.

The procedure and recovery

  • The stitch is usually placed vaginally under spinal, epidural, or general anaesthetic, and the procedure itself typically takes well under an hour.
  • Most women go home the same day or after a short overnight stay, depending on the hospital and whether it was planned or an emergency procedure.
  • Mild cramping, spotting, or period-type discomfort for a day or two afterwards is common and usually settles with rest and simple pain relief as advised by your team.
  • You'll likely be advised to avoid heavy lifting, strenuous exercise, and sexual intercourse for a period of time after the procedure — your team will give you specific guidance.
  • Follow-up appointments and scans monitor the cervix and check the stitch remains in place as your pregnancy progresses.
  • The stitch is normally removed around 36–37 weeks, or sooner if labour starts, your waters break, or there are signs of infection.

Getting support and what to watch for

Contact your midwife, maternity unit, or GP promptly if you notice any of the following after a cerclage:

  • Heavy bleeding, persistent pain, or fever
  • Fluid leaking that might suggest your waters have broken
  • Regular tightenings or contractions
  • Any symptoms that feel different or worry you

Waiting between appointments after a diagnosis of cervical weakness can be an anxious time — it's completely normal to feel on edge. Many women find it helps to talk things through with their midwife, a partner, or a pregnancy support group, and to keep a note of questions for each appointment.

Frequently Asked Questions

What is a cervical cerclage?

A cervical cerclage is a stitch placed around the cervix to help keep it closed for longer during pregnancy. It's used when there's a risk of the cervix opening too early, which can lead to late miscarriage or premature birth. It's usually placed in the first or early second trimester and removed later in the third trimester.

Is a cervical cerclage painful?

The procedure itself is done under anaesthetic, so you shouldn't feel pain while it's being placed. Afterwards, mild cramping and spotting for a day or so is common and usually manageable with rest and simple pain relief. If you experience severe or worsening pain, you should contact your maternity team.

Does having a cerclage guarantee I'll carry to term?

No procedure can guarantee an outcome, but a cerclage is used specifically because it improves the chances of continuing the pregnancy for women with a diagnosed cervical weakness. Your team will monitor you closely throughout with scans and appointments, and will discuss your individual risk and outlook with you based on your history and how your pregnancy is progressing.
