Patient's question:
Here is the English translation of your text, with line breaks preserved as instructed and all Chinese text translated into English:"It was yellowish-brown a few days before my period, and on the eighth day, it was watery with blood clots. Since my period has been irregular for seventeen days, how can I regulate it?"
Doctor's answer:
Hello, your menstrual period duration is long, and you have irregular vaginal bleeding, which may be caused by factors such as luteal phase deficiency. It is recommended that you undergo a detailed abdominal ultrasound examination to carefully observe the condition of the endometrium. You can use progesterone ointment to establish a normal menstrual cycle, and avoid sexual intercourse during vaginal bleeding. There are many treatment methods for this condition, but since the patient's condition varies, the treatment approach also differs. Therefore, it is necessary for the patient to seek professional medical attention as soon as possible for a detailed examination to prescribe the appropriate treatment.
