What Is Irregular Menstruation?

Menstruation occurs monthly in females. It is when the uterine lining sheds and fluid excretes from the vagina. Menstruation fluid contains blood, vaginal fluid, and tissue. Symptoms that can occur with monthly menstruation include uterine cramping, mood changes, and breast tenderness. Sometimes irregular menstruation can occur, where the menstrual cycle is off schedule.

Treatment for irregular menstruation includes taking medication or hormones. Common drug classes used to treat irregular menstruation are progesterones and progestins.
