Can I Take Primolut Nor And Duphaston Together To Delay My Period Since Duphaston Alone Doesn T Seem To Be Working?

hi .can I take primolut nor and duphaston at thesame time to delay my period ? I am currently taking duphaston alone but I feel like my period is in it’s way .please note that it’s my first time of taking duphaston for this purpose.on the contrary I have used primolut twice in the past to delay my period and it worked just fine .
