It may or may not be normal for your period to be gone after 2-3 days. The normal duration of menstruation is 3-7 days. If the period clears after 3 days, it is mostly within the normal range and does not require treatment. If the period clears in 2 days, it should be judged according to whether the menstrual volume is normal. If the menstrual volume is more than 20mL, there is usually no problem, indicating that the endometrium is normal and there is no need to worry. However, if the menstrual flow is very low, below 20mL, it may be caused by an endocrine disorder and no normal ovulation. It is also possible that the surgical operation in the uterine cavity has caused damage to the endometrium and uterine adhesions, when low menstrual volume and short periods may also occur, and such cases must be examined in the hospital.
