Clinical difference in spotting and a cycle?

Little back story, between sept and dec I didn't have a period. It was actually 100 days between cycles. I went to my OBGYN and he gave me Provera. I have been taking that since dec to induce my cycle. Well, today is CD 29 and for the past 4 days I have been spotting. Each time I wipe it varies from dark brown to bright red blood but never enough to even get on a pad. It is only evident when I wipe. But we are going on 5 days now... could this be considered my period or do I need to start my Provera for this month? I should also add, I've been taking opk tests and have never seen a positive one. And we've been TTC since June 😩
