Irregular menstruation came three times in thirty days, how to regulate

Patient's question:

Here is the English translation of your text, with line breaks preserved as they are:
"It's just that a few days before my period, it was yellowish-brown and had blood clots. I'm asking how to regulate irregular periods when they come three times in 30 days."

Doctor's answer:

Hello, based on your description, the initial consideration is unlikely to be cervical reasons, and the possibility of frequent menstruation is considered to be due to luteal phase deficiency. You can take progesterone capsules orally 5-7 days before your period and carefully observe the results.
You are married with no sexual history, and your hymen is intact, so transvaginal ultrasound and cervical examinations cannot be performed. There are many treatment methods for diseases, but since the patient's condition varies, the treatment approach also differs. Therefore, it is necessary for the patient to seek professional medical advice as soon as possible for detailed testing to accurately diagnose and treat the condition.
