Period or implantation?

I’m due for my period in a few days. And these past couple days I’ve been getting this. It’s light pink when I wipe but when I put my finger in and wipe it on a tissue (which are these pictures) it’s darker more red and slimy. I’m barely cramping and my boobs are mildly sore.

I’m usually cramping a lot on my period and before my period and I haven’t been cramping as much as usual.

There’s some moments during the day that I don’t get much blood. Like it gets less for a few hours then starts again, it comes and goes.

The picture of the liner is when I was wearing it all day today.
