The half-month interval between menstruation on the 20th and the 5th of the next month is in the ovulation period, which is mostly due to ovulation bleeding, but abnormalities such as cervical or endometrial lesions should also be excluded.
Intermenstrual bleeding occurs in the middle of two menstrual periods, i.e., during the ovulation period, when the amount of bleeding is obviously less than the amount of menstruation, due to the fluctuation of estrogen in the body caused by ovulation, causing part of the endometrium to fall off.
If bleeding occurs frequently 15 days after the onset of menstruation and continues unabated, it is recommended that the patient go to the hospital in a timely manner and be treated accordingly under the guidance of the doctor.
At the same time, patients should be alert to abnormal bleeding caused by cervical polyps, gynecological inflammatory diseases, precancerous lesions of the cervix or cervical cancer, endometrial cancer, etc. Although most of the cases of bleeding in the middle of menstruation are bleeding during ovulation, they should also pay attention to it, and come to the hospital in time to rule out the abnormality.
During the period of vaginal bleeding, it is important to prohibit sexual intercourse, prohibit baths, and pay attention to vulvar hygiene to avoid infection.
