Birth Labor Also: ROM

Rupture of membranes

Abbreviation: ROM

Rupture of membranes refers to the breaking of the amniotic sac, the fluid-filled bag surrounding your baby, releasing the amniotic fluid inside. This is commonly described as your waters breaking. It can happen spontaneously at the start of or during labour, or a doctor may break it deliberately to speed up labour in a process called artificial rupture of membranes. Fluid may rush out in a gush or trickle slowly and continuously. It is important to note the time it happens, and the colour and smell of the fluid. Clear fluid is normal, while green or brown fluid may indicate the baby has passed meconium, which needs prompt medical review.

What This Means for You

Understanding Rupture of membranes is an important part of your labor journey. When preparing for birth, understanding this term helps you discuss your birth preferences with your midwife or OB-GYN and know what to expect in the delivery room.
