Hi all just wondering if anyone else with pcos experiences long cycles and Ovulates late?

Last cycle I had a positive opk on CD 71 later had ovulation confirmed by bloods.
Af arrived 13dpo

This cycle I had a positive opk (4dpo now) do you think I should get bloods again to check progesterone to confirm?

My bbt chart and ewcm also show Ovulation occurred.

Has anyone been successful in conceiving this late in a cycle?

I take evening primrose oil cd1 (3000mgs daily) up to +opk daily prenatal, metformin (1000mg daily), mega B complex and 1500mg wild fish oil (3 x daily)
