I am taking norethisterone 5mg 3 times a day to delay my period, as I am getting married. It is working, but I want to know once I stop taking the tablets will my cycle have shifted ? I will obvioulsy have a bleed reasonably soon after, but will it them be a full 28 day cycle before I get my next one, or will I still be on my old cycle and get it 2 weeks later for a second time?
