Can AF just be spotting everyday??

So I got off my depo (only 1 shot and usually I get my period immediately if I miss a shot and I'm ttc so I'm not gonna get another shot)

And I started bleeding but not enough to fill up a pad. Enough to cover all my toilet paper when I wipe. But if i wipe again nothing is there. It's like that every day. For like a week now. And the past 2 days it's been very little but brown now.

Is this just the depo. Is it AF 🤷‍♀️ ovulation bleeding. Implantation lol. Idk what this is
