Patient's question:
I had my normal period from November 10th to November 16th. Ten days after the period ended (November 26th), I took the emergency contraceptive pill Yuzhentong. Four days later (November 30th), I had a small amount of dark red blood that lasted for four days.Question: 1. When should I start counting my next period cycle; 2. What are the possible reasons for not having a period for so long? (Multiple early pregnancy tests have confirmed no pregnancy, and I haven’t felt any physical discomfort.)
Follow-up question for the first question: Doctor: I’d like to ask again, my period started on November 10th, and after December 10th until January 3rd...
Doctor's answer:
Your condition may be due to menstrual irregularity, which can be caused by many factors, such as: endocrine disorders, external factors, nutritional status, psychological factors, drug factors, etc. If you have menstrual irregularity for a long time, it is necessary to get further examination to identify the cause of the irregularity. If it is due to organic lesions in the reproductive system, it can lead to infertility.
