Ovulation testing

Synita

Hi

I brought a clear blue ovulation kit the other day and I haven't a clue when to test as I have pcos. This month's cycle was 25 days which is a really good sign for me as I think finally my periods are trying to regulate itself naturally :) so do you guys think I should start testing from tomorrow as that's when it's telling me to test from or should I wait until my next cycle to start testing? I'm totally confused but then I'm also curious at the same time lol x
