PCOS & exercise

I no this sounds stupid but anyway 2 years ago I was dignosed with PCOS due to extreme weight gain I went for a 14/16 to 22/24 within a matter of years. Me and my partner was always having unprotected sex and we both question why I wasn't getting pregnant and it was the PCOS!! So we recently started trying For a baby I don't want any fertility drugs so I've been eating healthy lots of meats and salads I also been doing 30/45mins a day on a exercise bike is this to much exercise daily?? I've been pushing past the pain that I get with the PCOS and determined to get my BFP this year also I take mya insol folic acid and use pre seed...xx
