Help please ❗️❗️❗️TMI

So I posted this in another group and had 145 views no responses :( I really just need some insight..ok so my af is due 12/15 my af is always the same last for 4 days beyond super heavy filling up pads within an hour with clots(sorry tmi) anyways this month af came but it was different. Still four days, medium flow no clots...but what is really confusing me is I am spotting this is my third day..sometimes it's brownish sometimes pinkish and it's only sometimes when I wipe not everytime..my cm is creamy cervix high hard closed. Why would I be spotting this never happens...is there anyway I ovulated late or a strange implantation bleed? I've read where it's possible...is anyone out there with similar circumstances ?? The first picture is the color of it two days ago the second is a pic from this morning
