Implantation bleeding maybe

Hello so I know this will sound so confusing but I'm going to try my best to explain, this previous week I had my period but I'm usually heavy during my period and the blood is very thick and bright red but this time it was very light pink and I stopped as of yesterday 9/26 but today something odd has been going on, I had spotting early this morning but not enough to put a pad on but later this evening I checked my under wear and it was blood in them, but not a lot I didn't even feel it get there or come out? Now it's gone? I'm ttc for the first time and don't know if I'm just really wanting to be pregnant or is this implantation bleeding? Any advice? Or suggestions?
