Is it possible that bleeding occurred with 22 tablets of Drovelis?

If you took the first tablet on the first day of natural menstruation, irregular bleeding - occurring earlier than on white tablets should not worry. The first 3-4 months of using tablets are an adaptation period where the body adapts to the supply of hormones. During this period, spotting and mid-cycle bleeding may occur. If the medicine is taken correctly, you do not use other medicines that may weaken the effect of contraception, protection is maintained (even during bleeding and a placebo break - on white tablets). If the situation will be repeated after the 4th cycle of using the tablets, then it is worth consulting a gynecologist.
