Depo shot bleeding

Is it normal to bleed for a lot of days with the depo ? I got it in July so I'm due for the other but I'm not getting it I was spotting occasionally when i got it but now I'm bleeding everyday

I have been bleeding for 10 days today it's not heavy sometimes it's spotting pink then 2 days it was brown and now I'm bleeding kind of like a light period is that normal ?

And I'm so nauseous ugh and cramping 😌
