There was no blood the first time, but after a few days there was blood.

We know that because of the existence of the female hymen, there are often bleeding symptoms when having sexual intercourse for the first time. However, some women did not have any bleeding the first time, but had blood in their lower body after a few days. We need to analyze this situation separately. First, it is virgin bleeding, and then there is blood in the lower body. The key is to see whether there are other abnormalities in the body. Only a comprehensive judgment can make the situation clear.

There are several reasons why girls don’t get red the first time:

1. Since it is the first time, both men and women may be inexperienced or shy, which may cause the hymen to not rupture. In this case, it will not happen. The next few times the hymen ruptures, it will naturally bleed;

2. If a girl's hymen has been ruptured due to intense exercise such as high jumping, cycling, dancing, etc., there will be no bleeding during her first sexual intercourse.

What causes bleeding after sex?

Pelvic inflammatory disease. Pelvic inflammation can cause pelvic congestion. If the endometrium is congested and edematous, sex may cause the congested endometrium to release hormones, but this opportunity is rare.

Cervicitis or cervical erosion. 90% of married women suffer from cervicitis. Cervicitis is divided into three types: mild, moderate and severe according to the degree of cervical erosion. For patients with moderate or severe cervical erosion, the rubbing of the cervix by the glans of the male's penis during sexual intercourse may cause injury and bleeding. Because the amount of bleeding is small, it does not flow out immediately but accumulates in the vagina, and the color of the blood changes from fresh to old. Therefore, when the blood flows out the next day, it is dark red.

Cervical polyps. Chronic inflammation may cause cervical polyps due to long-term stimulation of the cervix. Single or multiple small pedunculated granulation tissues grow at the cervical opening, looking like bean buds, and the larger ones are as big as a finger. Polyps are fragile and tender, and will bleed if touched, so bleeding may occur after sexual intercourse. This bleeding is usually bright red.

Cervical cancer. Bleeding after sexual intercourse is the earliest symptom. Because there are more small blood vessels and the tissues are more fragile in the cancer lesions, the capillaries will rupture and bleed due to damage after each sexual intercourse. If the cancer grows further, it will bleed more easily.

The cervix of patients with early cervical cancer may not show obvious changes, or cancer and cervical erosion may exist at the same time. Cervical cancer bleeds easily when touched, mostly because the cervical cancer tissue invades the blood vessels in the interstitium. Postmenopausal women are prone to senile vaginitis due to the lack of estrogen. At this time, the vaginal mucosa becomes thinner and may be damaged during intercourse, causing bleeding.

Endometriosis. Some endometriosis grows on the cervix and appears as blue-purple nodules. If this blue-purple ectopic nodule is touched during sexual intercourse, it will cause bleeding. The amount of bleeding is generally small and dark red, and abdominal pain symptoms often occur after intercourse.
