Should I Take Medication To Get Periods?

Hello, I am suffering from Pcod since an year. I have had reagular period (35-40) day cycle. However this month I am late by 22 days. My doctor said I don t need any medication for treating pcod as I don t have any symptoms of it like weight gain, migrain etc.. should I take any medication like norethisterone to force my periods or wait for it to come naturally?? Thanks
