What should I do if my period is delayed?

Patient's question:

Menstruation lasts for more than 20 days, but the amount is not much

Doctor's answer:

First, avoid greasy foods such as fatty meats, fried foods, pastries, etc., and pay attention to controlling the intake of sugary foods. Secondly, strictly limit spicy foods such as chili peppers, pepper, raw onions, raw garlic, and alcoholic beverages. It is best to eat more foods rich in B2, B6, C, and E vitamins. At the same time, take traditional Chinese medicine for regulation.
