Menstrual disorders

Menstruation is a physiological phenomenon in women, characterized by periodic vaginal bleeding. The interval between two bleeding episodes is approximately one month, and each episode lasts about 2 to 8 days. If there is a change in the regularity of menstruation, it is called menstrual irregularity. The main symptoms include menstruation occurring more than 7 days earlier or later than expected, or excessive or scanty menstrual bleeding.
