Irregular cycle?

This post may contain TMI.

So, this is what I’ve logged as what I assumed was a period. I have PCOS and very irregular cycles when I don’t take anything for it. I’ve been taking Provera for the first 10 days each month to trigger a “period”. Previously I had used inositol to try to help with the PCOS and it has helped straighten out my cycle in the past. I started taking inositol again at the beginning of April. I chose not to take the Provera in June and had no period. I did take it in July because I didn’t want to have a period on my anniversary and started what I assumed was my period 7 days after finishing. It was pretty light, but frankly my periods have been a lot lately with the Provera. The second week it was a little heavier, and the third back to pretty light. Friday morning I had what resembled thick EWCM with several blood clots coming out of me (almost falling out) with severe cramping. Does this just sound like my hormones trying to straighten out or does this sound like maybe I was pregnant without knowing and miscarried? Would there be a point in taking a pregnancy test after bleeding for over three weeks or would it be pointless by now? Just looking for some advice and maybe someone to share a similar experience. This has been unusual for me.
