Concern about obstetrics and gynecology, menstrual irregularity concerns.

I'm worried about my gynecological health and irregular menstruation. When I was a student, my menstrual cycle was regular, but at some point, the dates became inconsistent. They say it could be due to stress, dieting, or lack of sleep, but if it continues to be irregular, I should visit a gynecologist for a check-up. Menstruation is uncomfortable, and irregularity makes me anxious, so I really need to take good care of my health.
