PCOS and spotting

So I was diagnosed with PCOS a couple months ago, I was put on progesterone back in September for 5 days and had my period on the 25th, I’m also on metformin. well I didn’t have a period in October. I started spotting November 2nd, than the 3rd I have raw egg white discharge along with spotting, than the 4th it was like a reddish brown spotting stopped for a couple hours late that night than came back yesterday still reddish brown but now the spotting is only when I wipe. Has anyone ever had this happen? I took a pregnancy test Sunday morning and it was negative, I’ve been extremely exhausted, backaches,nauseated,constipated,moody and crampy. I swear PCOS is the worst I feel like idk my body anymore... any advice would be greatly appreciated.
