Period M.I.A

Haven't had a period since the end of May it just up and disappeared up until then it was kinda regulated I've been TTC for some time still nothing...

All test are negative I only take Spironolactone 25mg for PCOS other than that I'm not sure why I haven't gotten a period I've tried tracking my ovulation but that's not going to well either I'm just over TTC at this point it's really frustrating...

I'm goin to see a new gyne in a few weeks is there anything specific questions I should be asking
