Ladies I need some help asap. My doctor hasn't called me back yet. TTC#1 first time with clomid.

My husband and I had planed on taking the first provera pill this Monday for inducing a period for clomid. Well, just yesterday I saw spotting and again today. (Obviously AF coming)

I have PCOS. My periods are few and far between and I'm not sure if I should start clomid on this cycle or wait a month and induce AF with provera so I can time it right. Any insight will help! Also you take clomid on the first full day of bleeding correct? Not spotting?
