what are the chances?

hello sisters, I am 20dpo, 7days late for AF. this morning i went to pee and I wiped seeing a pink thing, i wiped again and saw it a bit more. so far my symptoms of AF was a no show, rather ir was the opposite. Heavy bbs, tiredness and CMs non stop. temps were high too but i stoppes temping because I did not want to kill myself with it. Anyways, what should I call this light or medium bleeding? AF? or what? I am usually a very heavy flow person during AF, this one I can barely feel it. and last i checked it was just on a spot. I need suggestions please. was thinking of going in for a lab work if it would make any diff
