If a woman has brown leukorrhea after intercourse, it is often considered to be contact bleeding after intercourse caused by local problems of the cervix, and if brown leukorrhea occurs during pregnancy, it should be considered to be caused by pre-eclampsia or even ectopic pregnancy. The most common cause is due to local problems of the cervix, such as common cervical erosion, cervical polyps, cervical intraepithelial neoplasia, and even cervical cancer. If this is the time to have intercourse during ovulation, it should also be considered that the fluctuation of estrogen during ovulation decreases, resulting in a small amount of endothelial peeling, which causes ovulatory bleeding. The bleeding may last for 3 to 5 days, but usually not more than 7 days. At the same time, there will be obvious egg-white-like streaks of leucorrhea. If a woman has abnormal brown leucorrhea during pregnancy, she will not have her period because she is already pregnant.
Therefore, when a woman has a brownish white band, she should go to the hospital for ultrasound and internal examination to confirm the specific cause of the bleeding, and then treat the symptoms.
