Question.... my last period was on Nov 3rd last for the usual amount.... I have been off BC for almost a year and a half and have still been consistant ever since with my period starting the same time each month .... nothing has changed really except I was suppose to have my period on DEC 9th..... still nothing...I have been taking preg tests with them coming out as negative..... I have been emotional, moody, fatigued, random cravings, constipated, sensitive nipples and even some faint cramps/bloating from time to time.... pretty sure its not PMS....not sure if im just SUPER late for some odd reason or if im just getting false negatives ..... please help?
