Amniotic sac
The amniotic sac is a thin but tough pair of membranes, the amnion and chorion, that form a sealed, fluid-filled chamber around your growing baby inside the uterus. It protects your baby from bumps and pressure, helps maintain a stable temperature, and gives your baby room to move and develop normally. The sac usually ruptures at the start of labour, which is what people mean by "waters breaking." In some cases, doctors may rupture it artificially to speed up labour, a procedure called an amniotomy. A healthy, intact sac is essential for a safe pregnancy.
What This Means for You
Understanding Amniotic sac is an important part of your pregnancy journey. During pregnancy, your care team will use this term regularly. Being familiar with it means you can ask better questions and feel more confident at your antenatal appointments.

At KKH and NUH, if your waters break before 37 weeks (preterm prelabour rupture of membranes), you will be admitted immediately for monitoring and possible antibiotics to reduce infection risk.
