How to distinguish between ovulatory menstruation and anovulatory menstruation?
If menstruation is very regular, the longest interval between two menstrual periods is no more than 40 days, the shortest is no less than 20 days, there is blood for 3 to 7 days, and the blood volume is medium, then ovulation is generally occurring. This is because when the egg cell is discharged, the follicle wall turns into the corpus luteum. If the egg cell is not fertilized, the corpus luteum will shrink within 14 days. At this time, the endometrium loses the support of estrogen and progesterone, and will be ischemic, necrotic, and shed. So menstruation comes.
If there is no ovulation, there will be no corpus luteum, and there will be no progesterone. The endometrium is only supported by estrogen, but the amount of estrogen changes irregularly, sometimes more and sometimes less, and the endometrium peels off. It only depends on the fluctuation of estrogen levels. When estrogen levels drop, the endometrium peels off and menstruation is formed, so menstruation also appears irregular, with intervals up to several months and only a few days at the shortest. The condition of dripping menstrual bleeding can sometimes last for more than ten days. If this phenomenon occurs, then anovulation is almost certain.
