HELLO, welcome to hcm,
as per the details u have submitted,
as the urine pregnency kit is negative , it says implantation
diidnt occur .. and u took those duphaston
pills, generally after withdrawing of progesterone menstruation
occurs after 5-7 days ..so i hope u will get menstruation after 5-7 days from the date of stopping the duphaston pills..
hope i have cleared ur doubt...
