Why do I have black blood the next day after having sex during my ovulation period?

Many people choose to have sex during the ovulation period, because this period is the least likely time for women to get pregnant. However, many female friends find that they are bleeding black blood the day after having sex during the ovulation period. Many female friends are confused about this situation and don't know the reason. So, what is the reason for black blood flowing the next day after ovulation?

First, what's the matter with black blood discharge the next day after having sex during ovulation? In this case, because you had sex during ovulation, your menstruation is not very normal now. It may be a sign of threatened abortion after pregnancy. In this case, you can do an early pregnancy test yourself. If it is positive, it is a sign of threatened abortion. If it is negative, it is still normal menstruation. Pay attention to possible reasons such as sex hormone disorders, as well as possible reasons such as vaginitis and cervical erosion. Pay attention to the protection of the affected area. You can use Huahong wash to clean the affected area. If necessary, go to a regular hospital's gynecology department for examination to determine the cause, such as six sex hormone items, ultrasound monitoring, etc., and formulate reasonable treatment measures based on the examination results.

Second, vaginitis, or inflammation of the vagina, is a group of conditions that cause vulvovaginal symptoms such as itching, burning, irritation, and abnormal discharge. The vagina of a normal healthy woman has a natural defense function against the invasion of pathogens due to the characteristics of its anatomical tissue. For example, the closure of the vaginal opening, the close contact of the anterior and posterior walls of the vagina, the proliferation of vaginal epithelial cells and the keratinization of surface cells under the influence of estrogen, and the balance of vaginal acidity and alkalinity inhibit the reproduction of alkaline-adapted pathogens. The cervical mucus is alkaline. When the natural defense function of the vagina is destroyed, pathogens can easily invade and cause vaginal inflammation. Under normal circumstances, aerobic bacteria and anaerobic bacteria live in the vagina, forming normal vaginal flora. If the ecological balance between the vagina and the bacterial flora is disrupted for any reason, conditional pathogens may form. Common clinical diseases include: bacterial vaginosis (accounting for 22% to 50% of symptomatic women), candidal vaginitis (17% to 39%), Trichomonas vaginitis (4% to 35%), senile vaginitis, and vaginitis in young women.

Why do I discharge black blood the day after having sex during ovulation? 10% to 40% of patients with bacterial vaginosis have no clinical symptoms. Those with symptoms mainly show increased vaginal discharge with a fishy odor, which is especially aggravated after sexual intercourse and may be accompanied by mild vulvar itching or burning sensation. Examination showed no signs of congestion or inflammation in the vaginal mucosa. The secretions were grayish white, uniform, thin, and often adhered to the vaginal wall, which could be easily wiped off. 2. Candidal vaginitis (1) Vulvar itching, burning pain, and pain during sexual intercourse. (2) Frequent and painful urination. The characteristic of dysuria is that urine irritates the edematous vulva and vestibule during urination, causing pain. (3) Characteristic secretion: white, thick, and resembling curd or bean curd residue. (4) Vulvitis presents with geographic erythema, edema, and scratches. (5) Vaginitis may cause edema, erythema, and white membrane. 3. Trichomonas vaginitis (1) Characteristics of increased vaginal discharge: thin, purulent, yellow-green, foamy, and smelly. (2) Location of vulvar itching: vaginal opening and vulva. (3) If combined with urinary tract infection: frequent urination, urgency, pain, and sometimes hematuria. (4) Infertility: Trichomonas vaginalis can devour sperm, hinder the production of lactic acid, and affect its survival in the vagina. (5) Examination revealed: congestion of the vaginal mucosa with scattered bleeding spots, and a large amount of "strawberry-like" leucorrhea from the posterior fornix of the cervix, which was grayish yellow, yellowish-white thin liquid, or yellowish-green purulent secretions, often in a foamy state. There are no abnormal changes in the vaginal mucosa of carriers.
