There are many reasons for the bleeding of ruptured follicles during ovulation: 1, when the umbilical end of the fallopian tube ingests the egg, the follicle containing blood is transported to the fallopian tube, and retrograde to the uterine cavity will leave a certain amount of blood from the inside of the vagina, and most of the secretions that occur are bright red, dripping, or even brown, and won’t persist for too long.2, as the follicle secretion of the follicle or the existence of the follicle becomes too much at the time of ripening, the endometrial lining becomes congested and seeps blood, and there is also a certain amount of bleeding. The endometrium will be congested and oozing blood, and there will be some bleeding.3. After the rupture of the mature follicle, the level of estrogen in the body suddenly decreases, which can’t maintain the normal growth of the endometrium, and causes the surface layer of the endometrium to break down and fall off, resulting in bleeding phenomenon, which will be over in 3-5 days, and it won’t affect the body’s health. However, frequent occurrences will have an impact on conception, and it is necessary to check the endocrine hormone six, according to the situation to be adjusted to the cycle.
