What Will Happen As I Have Taken Clomig Instead Of Duphaston?

hi, i am 25 years old, 12 lbs. A week ago i was diagnosed to have polycystic ovaries because i have not gotten my period for 3 months. My OB prescribed me medications. Duphaston 10 mg once a day for 5 days. Once I get my period, on the second day of it, i will have to start taking clomid 50 mg for 5 days. Last saturday, i accidentally took clomig. instead of dupahston. So sunday i did not take any meds, monday i started with the proper prescribed procedure which's dupahston. today is the 5thday of taking duphaston and i have not gotten my period at all. its the last day of the duphaston. could there be something wrong? does this usually happen when taking duphaston? I mean I wont get the period right away?
