How to regulate when your period is delayed

Patient's question:

All symptoms: Less menstrual volume, pale color, slightly dark, sticky plasma
Onset time and cause: During menstruation
Treatment history: Never treated
Help desired: A herbal prescription for regulation

Doctor's answer:

Hello. This situation could be due to irregular menstruation, which is often caused by endocrine disorders. If you have had sexual activity, delayed menstruation could also indicate pregnancy. You can try using a good quality pregnancy test kit or have a blood test to check for human chorionic gonadotropin (hCG). As long as it's not pregnancy, there's usually no major issue. If the bleeding remains very light, I recommend you have a color Doppler ultrasound. On the second or third day of your period, have a fasting blood test for six hormone levels and thyroid function. Once the diagnosis is clear, treatment can begin.
In the meantime, avoid eating raw, cold, or spicy foods and avoid staying up late. About a week before your period, women should avoid raw, cold, and irritating foods. Drink more water and consume foods rich in fiber to keep bowel movements regular. During menstruation, you can help regulate your body by drinking brown sugar water.
