Patient's question:
Menstruation is delayed by 5 days. I went to the hospital for a blood test, and the hCG level was 0, which means I'm not pregnant either. But my period still hasn't come. What should I do?Doctor's answer:
Generally, the menstrual cycle is 28-30 days, and it is still within the normal range if it is advanced or delayed by one week. If there has been sexual activity, it is important to rule out the possibility of pregnancy first. The menstrual cycle of women is regulated by the hypothalamus-pituitary-ovary-gonadal axis. In addition to pregnancy, factors such as mental stress, emotional fluctuations, and changes in the environment; local inflammation, tumors, and developmental abnormalities of the reproductive organs; malnutrition, intracranial disorders, other endocrine dysfunction diseases, medications, and nutritional status can all cause dysfunction of this gonadal axis, leading to menstrual irregularities.
