I have vaginal bleeding one week after period and 3-4 days after intercourse. it has only been going on for about a day.

Vaginal bleeding: Abnormal vaginal bleeding occurs in up to one quarter of all women of reproductive age. Most of the times it is related to an imbalance in estrogen and Progesterone levels. There are infections and lesions of the cervix, vagina, and uterus that may also cause abnormal bleeding. Therefore, it is important to be evaluated to determine the exact cause. Annual gynecological exam is critical.
