How long after taking dydrogesterone tablets will menstruation start?

Dydrogesterone tablets are taken for 2 to 7 days to induce menstruation. They are primarily used to treat conditions caused by endogenous progesterone deficiency, such as secondary amenorrhea, menstrual disorders, dysfunctional uterine bleeding, endometriosis, and dysmenorrhea, or to prevent habitual or early pregnancy miscarriage due to insufficient progesterone during pregnancy. Before ovulation, the human body produces approximately 2 to 3 milligrams of progesterone per day; low levels of progesterone in the body may lead to amenorrhea or irregular menstruation. Therefore, it is best to take progesterone exactly as directed by a physician. At the same time, it is advisable to engage in appropriate exercise and maintain a relaxed state of mind.
