Opinions ??! Please ..

So I have PCOS and i’m not sure when or if I ovulated or even if i’m currently ovulating ... I take Medroxyprogesterone for periods , so usually the day after or 2 days after the last 5 day pill , I get AF . I am due for AF the 2nd or 3rd of March but i’ve been spotting yesterday & today .. today accompanied with cramps .. anybody have ideas on what it could be ?!?
