There are many reasons for spotting bleeding. For example, during ovulation, the endometrial lining may shed a small amount during the two peak periods of estrogen, causing the bleeding to be spotty. The bleeding usually lasts for about 3-7 days and can heal on its own without treatment. When the vaginal wall or cervix is irritated during intercourse, it may also cause spotting bleeding, which usually lasts for about 3 days and can heal on its own. When cervical erosion occurs, it can also be caused by heavy lifting or straining. When endometrial polyps or cervical canal polyps are present, they may also cause spotting bleeding. In this case, it is recommended to go to the hospital for a gynecological ultrasound to rule out any abnormalities in the endometrium, and depending on the situation, medication can be administered.
