Hello,
Welcome to ehealthforum
In polycystic ovaries the hormone dis-balance is such that there are long intervals in between two periods. The best way to regularize the periods in such a situation is to take oral pills and Clomid is the drug of choice.It does help in regularising periods and thus helps in conception.
Along with that if insulin resistance is presnet then metformin is also usually prescribed.Kindly continue with the prescribed treatment as it has to be taken regularly for long duration.Be in regular follow up with your treating doctor.
Take care!
