Can hormone replacement therapy (HRT) cause vaginal bleeding?


Women on combined estrogen and progesterone hormone replacement therapy (HRT) will likely have some menstrual periods.

Women on cyclical therapy usually have monthly bleeding but typically with reduced flow.

Women on continuous daily therapy tend to have irregular periods. Most of them experience random spotting during the first year of treatment. Some vaginal bleeding is normal and to be expected if you are taking HRT. Heavy, continuous vaginal bleeding, however, can be a sign of a serious condition such as uterine cancer.
