Your irregular periods and having multicysts are signs of PCOS. I have PCOS too. You doctor should put you on a protocol that would make you ovulate. They usually start with metformin and clomid. If that doesn't work they will move you to more aggressive methods.
There isn't really a cure for PCOS. But, most cases respond well to Metformin/Clomid combo. Some ladies only need Metformin to reduce cyst activity and resume ovulations. Others need a boost with Clomid.
