Is it normal to spotting for 3 weeks while taking Cyprodiol tablets?

If you have not previously experienced spotting while using Cyprodiol tablets, spotting appeared suddenly and lasts for 3 weeks, you should consult your gynecologist. According to the manufacturer: "Spotting usually resolves spontaneously or – in the case of intermenstrual bleeding of menstrual bleeding intensity – it can be inhibited within 4-5 days by administering ethinylestradiol as an auxiliary. If intermenstrual bleeding does not subside or continues, it is advisable to conduct thorough examinations with curettage to exclude organic diseases. The same applies to spotting that occurs at irregular intervals over several consecutive cycles or for the first time after prolonged use of Cyprodiol. In these cases, the bleeding is usually caused by organic changes, not by the product."
