PCOS but.......

Chastity

So a month or two back I started on a 10 day hormone pill + metphormin(6months) any way after the 10day pill I started my periods regular 2 months regular so far Any way the 3rd month it was a little early and shortened and a week later I been spotting light cramps could I possibly be pregnant? Wat is every ones thoughts? And how long should I wait before taking a pregnancy test!?
