I ve been on Yaz for six months but experienced irregular bleeding during the entire course. I consulted my doctor about it, but since it was 2 days before my next period was due I asked her to prescibe something to stop my period for a few days as we were going on a short vacation and I didn t want to be on my period during that time. She prescibed Qlaira to start using afterwards. I have started with qlaira and my period lasted almost 2 weeks, but when starting on the new pack I completely skipped my period. Is this normal?
