Im so confused

Every since my MC back in Oct my levels were still rising slowly. So I had to get a MX Shot in dec. I’m just trying to track my cycle and know what’s going on with my body but I’m hella confused. I’ve had spotting on and off this week..

Am i ovulating or what? Because I got dark lines like this already a couple days ago almost last week..SN: my periods are irregular so that doesn’t help one bit lol 🤦🏽‍♀️
