IF you do not want to use 'ovulation drugs', you can use temperature or ovulation predictor kits to verify ovulation.
With PCOS, you should not use temp alone, you do need to use an ovulation kit.
You could even try birth control!
Many women with pcos take birth control for 3- 6 months, then conceive shortly after they stop. It shrinks cysts, which really helps.
ANOTHER option is a diabetes drug called Metformin!
When taken by women with PCOS, they begin to ovulate NATURALLY AND REGULARLY within 3-5 months.
