It is very common and completely normal to experience a slight delay or temporary irregularity in your subsequent menstrual cycles after using norethisterone (Regestrone) to delay your period. Norethisterone is a hormone that temporarily alters your natural cycle. Once you stop taking it, your body may take one or two cycles to naturally readjust and return to its regular rhythm. There is no need to worry, as this is a temporary effect. However, if your period is delayed by more than a week or if you suspect pregnancy, a quick home test or a chat with your doctor can provide extra peace of mind.
