The loss of menstruation after two days is considered to be caused by endocrine disorders or gynecological diseases. Whether it is normal or not depends on the menstrual cycle and the amount of menstruation. The normal menstrual period is 3-7 days. If the menstrual bleeding clears after two days, you should first use an early pregnancy test to rule out pregnancy and bleeding due to preterm abortion. After ruling out, if the menstrual flow does not decrease and no other symptoms are combined, it can be considered to be related to the recent life style, diet, stress, drugs and environment. It is recommended to maintain a regular life style, eat a light diet, avoid cold and spicy food, avoid getting cold before menstruation and do not take hormonal drugs. Observe the next cycle to see if such situation occurs. If the menstrual volume also decreases at the same time, you should consider whether it is caused by endocrine disorder. It is recommended to go to the hospital for a sex hormone test and ultrasound to check if there are any abnormalities in the hormone level and endometrial condition. If there is any abnormality, timely symptomatic treatment should be provided. At the same time, after the menstruation is cleared, a comprehensive examination of other factors that may affect the menstruation should be done. For example, a pelvic examination, five A-factors, liver and kidney function, etc. Combine all the abnormal indicators to administer the right medication. If you have irregular menstruation, don’t panic, consult a doctor promptly to clarify the cause and follow the doctor’s instructions for symptomatic treatment.
