Does taking period-regulating medication affect menstruation?

Patient's question:

Irregular menstruation taking regulation medicine

Doctor's answer:

During the menstrual period, nourishing blood and invigorating blood circulation can promote uterine contractions, thereby increasing menstrual flow. Outside of the menstrual period, the focus should be on blood nourishment to increase the thickness of the endometrium, laying the foundation for menstrual flow during the period. Therefore, medication should be taken in both cases, but with different prescriptions. It is recommended to take the medication for at least 3 menstrual cycles.
Based on the symptoms you mentioned, it is considered to be a manifestation of endocrine disorders leading to hypomenorrhea. The main causes include kidney deficiency, blood deficiency, blood stasis, and other related factors. Treatment should involve syndrome differentiation and treatment, using traditional Chinese medicine for regulation. It is important to maintain a calm and pleasant mood.
