Ovulatory bleeding is different from menstruation. Perhaps your doubts will ensue: what is ovulatory bleeding all about? Why do you bleed during ovulation? Is bleeding during ovulation normal? Will bleeding during ovulation affect pregnancy? What should I do if I have bleeding during ovulation? What’s wrong with bleeding during ovulation? We all know that menstruation is caused by the shedding of the uterine lining, so what is ovulatory bleeding all about? In fact, its principle is the same as that of the menstrual period (or perhaps you can call it a sister-in-law). Ovulatory bleeding is a regular vaginal bleeding caused by a brief drop in estrogen levels, which causes the endometrium to lose its hormonal support and part of the endometrium to shed. Ovulatory bleeding is mid-menstrual bleeding, which is a small amount of bleeding between two normal amounts of periods and can be accompanied by varying degrees of small abdominal pain. Like menstruation, it is accompanied by abdominal pain and other symptoms. However, the amount of blood discharged during ovulatory bleeding is relatively small, and some of it is only coffee-colored discharge. Generally speaking, ovulatory bleeding can stop on its own in 2-3 days, up to 7 days. The main causes of ovulatory bleeding are as follows: 1. Excessive fluctuations in hormone levels. After ovulation, the estrogen level drops rapidly, causing the endometrium, which is affected by estrogen and shows a proliferative response, to lose support and bleed a little. 2. Chronic inflammation of the endometrium, which causes endometrial congestion during ovulation, or when ovulation happens to occur, the blood vessels on the surface of the ovary rupture and bleeding increases compared to normal and refluxes to the uterine cavity with the peristalsis of the fallopian tubes and is discharged out of the body through the vagina. Is bleeding during ovulation normal? Whether ovulatory bleeding is normal or not depends on the amount of blood discharged and other accompanying symptoms. When examining the cervical canal mucus at mid-menstruation in women with ovulation, about 60% of the mucus is found to have red blood cells under microscopic observation, but no bleeding that may be seen with the naked eye is not pathological and is normal. The duration of vaginal bleeding visible to the naked eye may appear for a few hours, or 3-5 days, but rarely reaches more than 7 days. In some cases, the bleeding during ovulation is very small, with a few drops of blood, or blood in the band, and in general rarely reaches the menstrual volume. The bleeding may be accompanied by discomfort or vague pain or pain on one side of the lower abdomen, even involving the lumbar region and the inner femur. The symptoms may occur continuously every month or once every other month, in some cases several months in a year, and in some cases only once in a lifetime. So in general, if ovulatory bleeding lasts less than 7 days, is not incessant, and is not accompanied by pain equal to that of menstrual cramps, it is basically normal. However, there are still some severe cases that may last until the next menstrual period. In this case, it is time to find relief and treatment. Therefore, in general, ovulatory bleeding is minimal and has no effect on the body, so there is no need to treat it and it does not affect conception. If the bleeding is heavy and lasts for a long time, it can be considered as a phenomenon of menstrual irregularity and needs to be treated by a doctor; other diseases of the reproductive tract such as cervical erosion, cervical polyps and submucosal fibroids must also be excluded.
