Is it normal that I have a period while using Activelle tablets?

According to the manufacturer: "During the first months of treatment, bleeding or spotting may occur. If bleeding persists after the first months of treatment, occurs some time after the start of treatment or persists after its completion, the cause of bleeding should be accurately diagnosed by performing an endometrial biopsy to rule out cancer. "Therefore, such a state should not be alarming. However, if bleeding also occurs in the following months, it is worth consulting a doctor.
