I started my period on my own (without provera - I have PCOS and very irregular anovulatory

cycles) on 2/28. I had my 4 or 5 days of bleeding and since then have been spotting, started out brownish red and now is just red. I’m still having red spotting. I just feel confused. I was so happy I started my period on my own, but I feel like something’s wrong that I’m still spotting.

I took a clearblue test this morning (not FMU) and got what appear to be a vvfl but I know blue dye is notorious for evaps and false positives. Is it even possible that I could be pregnant? I bought pink dye tests a little bit ago and will be taking one tomorrow morning.
