Menstruation occurred again after taking dydrogesterone tablets for half a month
Having a menstrual period after taking dydrogesterone tablets for half a month may be due to incorrect medication use, natural menstruation, or failed pregnancy preservation. Targeted treatments are required, with specific analysis as follows:
1. Incorrect method of administration
If doses are missed or the medication is discontinued during treatment, withdrawal bleeding may occur, which resembles menstruation. This results from a drop in hormone levels. It is recommended to visit a hospital and follow the doctor's instructions for proper drug use to prevent recurrence.
2. Menstrual onset
If a woman’s body is unaffected by the medication, menstruation may naturally occur. In this case, the medication should be stopped promptly to allow normal menstruation. If continued use is desired, it can be resumed during the second half of the menstrual cycle, which may help repair the endometrium to some extent.
3. Failed pregnancy preservation
If dydrogesterone tablets are being used to treat threatened miscarriage caused by progesterone deficiency, this situation may arise when pregnancy preservation fails. Bed rest is necessary, and immediate medical attention should be sought for further treatment.
Besides the above, conditions such as endometrial hyperplasia, ovarian cysts, and polycystic ovary syndrome (PCOS) can also cause this phenomenon. It is advisable to seek timely medical evaluation to determine the underlying cause.
