During this period of time in the clinic, several cases of intermenstrual bleeding were encountered consecutively, and the patients were annoyed because they were nervous. In fact, bleeding between periods is not rare, nor does it mean abnormal. It occurs in the middle of two menstrual periods, i.e. ovulation, and usually lasts from a few hours to a few days, some of which are interspersed with leukorrhea, usually in small amounts, and very rarely up to the amount of menstruation. As the mature follicle ruptures and ovulates, estrogen levels drop briefly, causing the endometrium to lose hormonal support and some endometrial shedding, resulting in regular vaginal bleeding. And with the formation of the ovarian corpus luteum, which secretes sufficient amounts of estrogen and progesterone, the ulcerated endometrial surface is rapidly repaired and the bleeding stops. Occasional bleeding between periods is not harmful to the body, many may be due to overwork, abnormal mood swings, changes in the living environment or low immunity of the body affects the endocrine balance, we just need to pay attention to regulate it. However, if bleeding occurs frequently during ovulation, endocrine disorders should be considered, and some estrogen supplementation drugs can be used under the guidance of a doctor. If the bleeding is excessive, even more than the normal menstrual flow, and lasts for a long time, it is best to do hormone six tests on the third day of menstruation and vaginal ultrasound 3-5 days after menstruation, in order to clarify the diagnosis and symptomatic treatment. In addition, during ovulation bleeding, you should rest more, avoid overwork; usually enhance physical exercise; and keep clean to prevent infection. During the bleeding period should be prohibited to eat spicy and stimulating food, avoid eating onions, garlic, leeks, ginger and other stimulating things that transport fire. So as not to prolong the time of ovulation bleeding.
