Threatened preterm labour: what to know

Threatened preterm labour means contractions or cervical changes may signal early labour, so prompt maternity assessment is needed. Symptoms can settle, but only an examination can clarify what is happening.

Possible signs include repeated tightening, period-like cramps, low backache, pelvic pressure, a change in vaginal discharge, bleeding, or leaking fluid. The maternity team may check your contractions, cervix, membranes, infection symptoms, and the baby’s wellbeing.

Threatened preterm labour is not the same as confirmed birth being imminent. The team may observe you and arrange tests to see whether contractions are affecting the cervix. Read more about Preterm Labour for the wider condition and its possible course.

Call your maternity unit promptly if you have regular tightenings, fluid leakage, bleeding, pelvic pressure, or persistent backache. While arranging care, note when tightenings start and whether they become closer together. Do not drive yourself if you feel faint or unwell.

Assessment may lead to monitoring, fluids, treatment for an infection, or medicines chosen for your gestation and clinical findings. An Antenatal Steroid Injection may be discussed when early birth is a concern. A Cervical Cerclage is relevant only in selected situations involving the cervix.

Seek immediate maternity care for suspected waters breaking, bright-red bleeding, severe pain, regular or strengthening contractions, reduced fetal movement, fever, or a strong urge to push. Do not wait for symptoms to become unbearable; early assessment can guide monitoring and treatment.

Ask whether your cervix or membranes have changed, what monitoring is planned, which symptoms require a return visit, and whether steroid treatment or other measures are appropriate at your stage of pregnancy.
