If you have a small amount of vaginal bleeding again 15 days after your period ends, consider it ovulatory bleeding. At the time of ovulation, the endometrium loses its estrogen support due to the temporary drop of estrogen, and the endometrium is shed, causing a small amount of vaginal bleeding. This vaginal bleeding usually clears up in 2-3 days and the amount is significantly less than the amount of menstruation, which can clinically stop on its own without intervention. Because the estrogen level rises after ovulation and the endometrium is supported by estrogen, the bleeding will gradually stop. For ovulatory bleeding, treatment is usually given, starting from day 8 or 10 of the menstrual cycle, you can take oral supplement Glaxo for about 7 days. You can also take a small amount of hemostatic medication, such as Anlactin.
