Doctor's answer:

Hello, based on the situation you described, you haven't had your period for 40 days. If pregnancy can be ruled out, your condition falls under menstrual irregularity. If your period continues to be absent, you can go to the hospital and, under the guidance of a doctor, use progesterone to induce menstruation. You should pay attention to rest and avoid excessive stress. Do not eat spicy or irritating foods, avoid contact with cold water, and avoid washing your feet with cold water. Also, avoid eating spicy and cold foods. You can try brown sugar water. Brown sugar is warm in nature and has a warming effect, which can help to unblock meridians and aid in the expulsion of the menstrual flow.
