Well since getting off of them ive been able to ovulate since I havent in the past year and a half.Well my cycles has always been 28 days and now since gettin off my 1st real period was last month November 15 well this month I havent had a period yet and today is day 31 well since the begning of this month ive been getting cramps that would come and go like my period was going to come but I know my period was only like 7-8 days away and my are always sore a week b4 my period comes and my s didnt start to get sore till Thursday and it lasted till yesterday but still no period and ive been nausea as hell since Friday.
