It is the end of the month. What if menstruation hasn't come yet?

According to the research, the cold stimulation of women's menstrual period will cause excessive contraction of blood vessels in pelvic cavity, which can cause oligomenorrhea and even amenorrhea. Therefore, women's daily life should be regular and avoid overwork, especially during menstruation.

Long-term mental depression, sulking or suffering from major mental stimulation and psychological trauma can all lead to menstrual disorder or dysmenorrhea and amenorrhea. This is because menstruation is formed by stimulating endometrium with hormones secreted by ovaries, and the hormones secreted by ovaries are controlled by hormones released by pituitary and hypothalamus, so whether the function of ovaries, pituitary or hypothalamus is abnormal, it will affect menstruation.

Therefore, women who pursue slim figure must not blindly diet.
