What’s wrong with the blood? It’s gone in two days.

In this context, coming refers to menstruation. Menstruation lasts for two days and the bleeding stops. It may be a normal physiological phenomenon, or it may be caused by cold, or it may be caused by menstrual disorders, pre-miscarriage and other reasons.
1. Physiological phenomenon: Normal women’s menstruation lasts 2-8 days. If a woman usually has a regular menstrual cycle and normal menstrual flow, and occasionally has a menstrual period that lasts for two days and then stops, it may be a normal manifestation.
2. Cold: If a woman eats too much cold food or wades in the rain during her menstrual period, it will stimulate uterine vasoconstriction leading to a decrease in menstrual flow.
3. Menstrual disorders: If a woman’s endocrine system is recently disrupted, resulting in menstrual disorders, she may experience shorter menstrual periods or reduced menstrual flow.
4. Pre-eclampsia: If a woman of childbearing age who has recently had sexual intercourse experiences a menstrual period that lasts for two days and then stops, she needs to be alert to the fact that the bleeding is not a true menstrual period, but a sign of pre-eclampsia.
If any of the above symptoms occur, it is recommended to go to the hospital in time.
