How to delay menstruation for a few days

　　"Aunt" usually refers to menstruation. Generally, methods to delay menstruation by a few days include avoiding external adverse stimuli, engaging in moderate exercise, taking oral short-term contraceptives, using progestin medications, and receiving progesterone injections. Detailed explanations are as follows:

1. Avoid External Adverse Stimuli

　　When the body is exposed to cold, it may cause pelvic blood vessel constriction through neuroendocrine regulation, affecting blood supply to the endometrium and potentially leading to earlier menstruation. Excessive sadness, anxiety, and other emotional disturbances can also interfere with hormone secretion, causing changes in the menstrual cycle. Avoiding these adverse stimuli as much as possible can increase the likelihood of successfully delaying menstruation.

2. Moderate Exercise

　　Appropriate physical activities such as jogging, yoga, and walking can improve blood circulation, regulate metabolic functions, and positively affect the endocrine system. These activities help maintain hormonal balance and reduce menstrual cycle fluctuations. However, it's important not to overexert oneself during exercise.

3. Oral Short-Term Contraceptives

　　Short-term contraceptives regulate hormone levels to inhibit ovulation and alter the endometrial environment, achieving both contraceptive effects and menstrual cycle regulation. To delay menstruation, these pills—containing estrogen and progestin—should be taken regularly starting before the expected menstrual period, maintaining relatively stable hormone levels in the body. This prevents the endometrium from shedding and thus delays menstruation. However, they should be used under medical guidance.

4. Use of Progestin Medications

　　Progestin transforms the endometrium from the proliferative phase to the secretory phase. Continuous supplementation of progestin helps maintain the endometrium in the secretory phase, preventing its shedding and thereby delaying menstruation. Examples include progesterone capsules and dydrogesterone tablets.

5. Progesterone Injection

　　Administering progesterone via intramuscular injection rapidly elevates the body's progestin levels, more directly and effectively maintaining the endometrium in the secretory phase and delaying menstruation. However, injections may cause some discomfort or pain, and similar adverse reactions to oral progestins may occur, such as local hardening and dizziness. Long-term or excessive use may also affect liver function. Therefore, their use must be standardized under a doctor's guidance.

　　Self-induced menstrual delay may carry certain risks, so it is recommended to proceed under medical supervision.
