af ended on Sunday

Marcy
Af ended on Sunday but since then I've been having this kind of discharge (pic in comments). I know it's old blood but usually I don't have this after af especially for this long. Could It mean I have a hormone imbalance? I just want my rainbow baby😢This is so frustrating because I'm coming up on my ovulation window and I think I'll be out because this cycle is so weird. I have been getting positive opk's since I took the first one a day after af ended. Someone help!!
