No period after 10 days of progesterone?

Hey, ladies. Very confused here. So here's the story: I have PCOS (obviously, as I'm in this group) and had a m/c at 5.5 weeks August 24th after 8 months ttc. Cycle was still out of wack. Started taking Myo-inositol. Got a positive digital opk (finally - on Sept 27th). Then no period. Dr. gave me a weeks worth of Provera, and now it's day 16 AFTER finishing Provera and still no period. What does this mean? I feel like it's a bad omen... I should mention that I had some bright red bleeding on day 3 of Provera that lasted a day or two, then turned into brown spotting, but not enough to count as a full period. Help!
