Patient's question:
NoDoctor's answer:
The menstrual cycle of women is regulated by the hypothalamic-pituitary-ovarian-gonadal axis. Except during pregnancy, various factors such as mental stress, emotional fluctuations, environmental changes, diseases, medications, and nutritional status can disrupt the function of this gonadal axis, leading to menstrual irregularities. Antibiotics have little impact on women's menstruation. A delay or advancement of about one week in the menstrual cycle is considered normal. If no contraceptive measures are taken during sexual activity and the menstrual period is delayed by more than 10 days, pregnancy should be considered, and medical examination in the gynecology department is necessary for blood HCG and ultrasound tests to confirm the diagnosis.
