How long after a D&C for dysfunctional uterine bleeding can one expect to have their next menstrual period?

Patient's question:

Medical History
On January 17, 2012, a D&C (dilation and curettage) with IUD removal was performed.
Test results: Hypoestrogenism due to dysfunctional uterine bleeding.
Previous treatment and effectiveness: Applied medication three days later.
What kind of help is needed: Menstruation has not arrived this month.

Doctor's answer:

Hello, low estrogen levels may lead to menstrual disorders. For your IUD removal, it may also cause endocrine disorders and result in menstrual irregularities. It is recommended that you take progesterone to regulate your menstrual cycle. Additionally, you can take Wuji Baifeng Pill in combination for treatment. Moreover, patients should develop a regular lifestyle, persist in treatment, maintain a light diet, and engage in aerobic exercise to boost their immunity and reduce the risk of illness.
