Standard 1: The menstrual color is dark red. Fresh menstrual blood is really bright red, but it is normal to be oxidized by the external environment and turn dark red after staying in sanitary napkins and other items for a period of time.
Standard 2: Regular menstrual cycle. The menstrual cycle generally ranges from 2 1 day to 36 days, with an average period of about 28 days. If some friends come twice a month, it is likely that the fallopian tubes are blocked or other reasons. Moreover, the period of menstruation will not be long, generally speaking, it is 3 days to 7 days, with an average of about 5 days. If menstruation is delayed and it is unclean for more than 10 days, you need to go to the hospital for examination.
Standard 3: Appropriate menstrual flow. Generally speaking, it should be enough for female friends with normal menstruation to change 3 ~ 5 sanitary napkins every day during menstrual cramps. If the menstrual flow is too much, even if it is covered with sanitary napkins or even dripped to the thigh root within one hour, it is very abnormal and needs to be paid attention to.
Standard 4: Menstrual blood does not coagulate. Normal menstrual blood will not coagulate, and there will be other substances in the discharged waste, such as some fragments falling from the endometrium, which is normal.
If menstruation meets the above four criteria, generally speaking, your body is in a healthy state. If it does not meet the standard, it needs to be taken seriously and go to the hospital for examination if necessary.
