### Patient: Doctor, I've been having unpredictable menstruation for some time now. I also experience vaginal itching, and when I have my periods, they last unusually longer than before. But then I also have this problem of completely missing my period for a couple of months.
### Doctor: Based on your symptoms, it appears that you might be suffering from a condition known as idiopathic painful menstruation, which is also known as dysmenorrhea.
