What can cause vaginal bleeding?

Mother's hormones: When babies are first born, they have been growing in the presence of their mother's female hormones. After birth, the withdrawal of these hormones may cause a little bit of vaginal spotting for a few days, which is entirely normal.

Many possibilities: There are many causes of abnormal vaginal bleeding. This includes medical causes, such as thyroid disorder or hormonal imbalances or undue stress. In addition, physical causes, such as a tear or laceration, polyps, fibroids, or even cancer. This is very dependent on age, medical history, and physical examination.
