I took norethisterone to delay my period for a holiday in April, and my period came 3 days after I stopped (16th April). On May 21st, my period didn't come as expected (my cycle is usually longer than the usual 28day cycle, about 35days-40days). However, I had browN discharge on and off for about 2 weeks. Until now (22nd June) my period has not come, and there has only been white discharge since early June. Am I pregnant?
