TMI, implantation or early light period?

So, I started VERY lightly bleeding just like this yesterday. It gets just a tad bit heavier and a little more pink. If I wasn’t paying attention I probably wouldn’t notice. But I pay attention very closely because I’m ttc. Do you guys think this could be implantation? I’ll take a test in about 3 days to be completely sure.

So, update, I’ve been bleeding still but it’s literally on and off. I’ll wipe and there will be a decent amount on there then for hours there’s nothing. This morning when I woke up there was hardly anything. I don’t know what to think.
