TTC as a competitive swimmer

St
I have PCOS and my BMI is over 30... It sucks because I can work about 3x or harder than anyone without PCOS and only lose a tiny bit of weight...
Anyways- I have been a swimmer since I was 12. Currently I swim for a Masters club team. On average I swim at least 4, if not 5 times per week with each workout over 2,000 yards or meters (depending on the day).
My question: is there anyone out there who also swims and is TTC and what is it like for you?
