If I didn't have bleeding with Cliovelle, and after changing to Femoston mite I bleed again - should I go to the doctor?

At the moment, there is no reason to worry. After changing tablets, bleeding may occur - this is a temporary situation. This symptom should disappear with the duration of treatment. The bleeding you observe is not a natural menstruation, but artificially induced bleeding associated with the supply of hormones. Transient bleeding and midcyclic spotting may occur during the first months of treatment. If bleeding or spotting occurs later or persists despite discontinuation of treatment, diagnostics should be performed, which may include an endometrial biopsy to determine the cause of bleeding and rule out endometrial cancer.
