In PCOS, a hormonal imbalance often means your body doesn't produce enough progesterone to regulate your cycle. This causes the uterine lining to build up and shed irregularly. Medications like Sysron N and Regestrone contain norethisterone, a synthetic progesterone. This hormone steps in to stabilize your uterine lining, mimicking your body's natural signals to control and stop the bleeding. It is very common to need this support.
