Help? Implantation bleeding ???

Okay so my last period was on march 7th. For the last 4 days(today day 4) I have nothing when I wipe or if I do it’s very little pink. But when I do the finger test (sorry) it normally looks like the picture. It is a little heavier in the morning. Kind of like a rust color but it’s never in between that. It’s very sticky and odorless. I’ve also been having the following symptoms:

Frequent urination

Very tender breasts

Darker areola

Mild cramping(I never cramp)

Headaches

I’m currently 11dpo with af arriving April 6 or 7

Please help??
