What should I do if my period does not occur after taking dydrogesterone tablets?
Menstruation is a hallmark of female sexual maturity; its onset typically signifies a healthy body and normal fertility. During menstruation, in addition to vaginal bleeding, women commonly experience other symptoms such as fatigue, headache, and loss of appetite. So what should you do if your period does not occur after taking dydrogesterone tablets?
What to Do If Your Period Does Not Occur After Taking Dydrogesterone
Failure to menstruate after taking dydrogesterone may indicate pregnancy, insufficient estrogen secretion, or other underlying causes. If pregnancy has occurred, menstruation will not ensue following progesterone administration. For dydrogesterone to effectively induce menstruation, adequate endogenous estrogen levels—and consequent sufficient endometrial proliferation—are prerequisites. Once administered, dydrogesterone triggers endometrial shedding and subsequent bleeding. Other potential causes include uterine, ovarian, pituitary, or hypothalamic disorders. If no menstrual bleeding occurs after dydrogesterone use, an early pregnancy test should be performed first to rule out pregnancy, followed by medical evaluation at a hospital. A physician can identify the underlying cause and recommend appropriate menstrual-regulating treatment.

If menstruation fails to occur after taking dydrogesterone, pregnancy must first be excluded. Pregnant women who discontinue dydrogesterone will not experience menstrual cramps; therefore, serum β-hCG testing and gynecological ultrasound are essential to confirm or exclude pregnancy. Secondly, certain pathological conditions—such as pituitary adenoma, hyperprolactinemia, or polycystic ovary syndrome (PCOS)—may cause amenorrhea, and dydrogesterone administration will not induce menstrual cramping in these cases.

Patients are advised to avoid drinking cold water and consuming spicy foods during menstruation. We hope this information proves helpful.
