Does Duphaston Help In Getting Periods When Pregnant?

Hi, i am 5 days delayed now, im given duphaston 10 mg by my OBGYN of which i was explained for what it is, but im worried because i already done my pregnancy test and its positive. I already have 3 kids, a third yr college, a first year high school and a nursery.Its a big concern for us because we are are abt to migrate to canada. Can the drugs that i take will help me menstruate?
