How Often Should We Check For Pcod?

I was told i have pcos when i got abortioned. I am now taking Hyponid(1-0-1) from January,Benforce-M(1-0-0), Chrominac-A(0-0-1) from April and Yasmin (21 tablets) for 3 months. I was having 64 kgs after my abortion. Now I am taking regular diet and exercisea and my weight reduced to 61 kgs.I didn't check the condition of disese after april. How often do i have to check for pcod? Through my study i got the information that if we have correct weight and regular periods then the pcod is gone. Is it right?
