Period after depo

Quinn

So my last depo shot was in may 2020. I didn’t take another one so it ended in August 2020. Occasionally since then I would bleed a little here and there but last month I bled for a week a heavy cycle. And then I was late with the next period by 10 days and have only spotted since then but it’s been going on for 8 days and I’m freaking out. What’s happening?!
