HELP PLZ

Ok so I'm finally regular with AF and she left on the 8th ( about 4 days ago) I went to pee a little bit ago and had lite pink when I wiped and when I checked my CM its mixed with it. This has never happened to me before when AF is gone its normally just gone no spotting or anything at all. Just wondering if anyone else has had this happen and it end up being implantation bleeding. I have a heavy flow so its totally not normal for me to spot at all and its never lite pink??? I need some answers ladies. Please and thank you!!
