I started taking norethindrone 7 days ago to delay my period (which was due to start on wed, it's sat and no period) so it has worked the way I want. My question is, I want to stop taking it (because I'm 50, obese and worry about getting blood clots) but I've heard the period afterwards is very heavy and can last for an extended amount of time. Has anyone else used it for a short period of time and if so what was your period like afterwards?
