Hi doctors, I am taking duphaston to regulate my period, and i am trying to conceive. On addittion to glucophage. Last month i decided not to take duphaston in order to check if i will get my period by my own, and i didnt, home pregnancy test showed negative. Then i took duphastion 2 pills per day for 5 day, its my 5th day after my last pill, and still didnt get my period. I need an advice, what should i do? And why this happenned? Thanks
