A woman's period begins at puberty and will not disappear until end of menopause. The status of menstruation not only reflects strength of fertility, but is also a "barometer" of women's health. If you experience a menstrual irregularity, you will go to hospital on time for treatment in order to avoid more serious diseases. Then, whether fertility is strong or not, we can see four main signals before menstruation.
If there are four main signs before you come to your aunt, your fertility is very good.Signal 1, woman has no abdominal pain

Many girlfriends experience abdominal pain from 1 day before menstrual cramps to 2 days before menstrual cramps, most of which are caused by dysmenorrhea or irregular periods caused by a cold. If your stomach does not hurt at this time, then you do not have a palace cold. A warm uterus will facilitate onset of a “good pregnancy”!
Signal 2, menstrual blood color is normal
Menstrual blood has a peculiarity, that is, it does not thicken, and its color is dark red. Because in menstruation there is not only blood, but also substances such as endometrial fragments, cervical mucus, and vaginal epithelial cells. Although blood is bright red, after blood is stored on a sanitary napkin for a period of time, oxygen in air comes into contact with iron in the blood and oxidizes, so it turns dark red. Is your menstrual blood normal?
Signal 3, normal menses

The total menstrual flow in women is from 50 to 200 ml, no less and no more than this amount. Too little or too much will have a certain effect on body of girlfriends, and can also reflect health of uterus to a certain extent. If you feel like amount cannot be measured, an easy way is to see if sanitary napkin is changed 3 to 5 times a day in 3 days before your period, and if it is, then it's okay.
Signal 4, menstrual regularity
As a general rule, a woman's menstrual cycle is counted from day before her menstrual cramps until her next period. This cycle varies from person to person, usually between 22 and 36 days, and for most people it is around 28 days. It cannot be too short and it cannot be too long. Otherwise, gynecological diseases may occur in body, which can affect conception. The duration of menstrual cramps is usually 4 to 7 days, with an average of about 5 days.

Menstruation is very important for women. Whether you want to have children or not, you should pay attention to your menstrual conditions in time. Symptomatic treatment of actual situation can lead to a speedy recovery.
