Implantation?

Since Friday morning I have been spotting mostly just when I wipe, it’s a light pink color and some drops will come out when I pee but not much and not clumps of blood, but after having intercourse and I go to pee and wipe there is Brown Mucas Looking blood, has this happened to anyone?

And how long can sporting last? I’m still spotting Today and my period isn’t supposed to arrive until Thursday
