If you are bleeding again on the third day after having intercourse less than ten days after your period, it may be caused by ovulation bleeding, cervical disease, or pregnancy.
1. Ovulation bleeding: generally occurs in the next menstrual period about 14 days before the onset of bleeding, usually bleeding 2 ~ 3 days, usually bleeding less than the amount of menstruation, occasionally accompanied by pain or discomfort in the lower abdomen.
2. Cervical disease: Cervical bleeding may occur when there are polyps and other lesions on the cervix, usually with less bleeding, and may occur at any time during the menstrual period.
3. Pregnancy: Abnormal vaginal bleeding needs to be ruled out in case of pregnancy. It is possible that the previous period was also characterized by abnormal bleeding, and the uterus was stimulated after coitus, leading to bleeding again. Ultrasound and blood HCG tests can usually confirm the diagnosis.
There are many possible causes for abnormal vaginal bleeding, so you need to consult a doctor to determine the cause of the problem and deal with it under the doctor’s guidance.
