Normal women’s menstruation advance or delayed up to 7 days are normal, and with the woman’s life sleep, diet, mood, work, life stress, labor conditions are related to the woman’s follicle development, ovulation, or even anovulation. If a woman’s period is delayed for 5 days, on the basis of ruling out pregnancy, further temporary observation can be made. If it is obviously delayed for 10 days, or even more than half a month, further ultrasound is needed to clarify the diagnosis, and reproductive hormone examination is needed to exclude ovarian and hypothalamic amenorrhea if necessary. If the lining of the uterus is thin, it can be adjusted to menstruation by supplemental Jiale or progesterone; if the lining of the uterus is thick, progesterone can be used directly to promote menstruation and then observe. If there is no improvement after adjusting lifestyle habits, further examination is needed.
