After what time should menstruation appear after discontinuation of Yaz?

If you have discontinued Yaz tablets by taking all the tablets from your current blister, you should experience withdrawal bleeding during the 4 days of using the white placebo tablets. In a situation where you do not start the next pack of hormone pills, i.e. in the absence of hormone supply "from the outside", the body returns to physiological tracks and the next menstruation should appear simply after the end of the cycle, i.e. in about another month. However, sometimes the natural menstrual cycle does not return immediately. Sometimes amenorrhea or irregular menstruation can occur even for a period of several months. It is difficult to answer unequivocally how this situation will turn out in your individual case - the length of contraception use and age may not matter so much.
