Af or implantation bleeding? Help🙁

So Thursday night I started noticing light pink blood when I wiped.. woke up the next morning still no blood.. Around 10am Friday I thought it was af it was SUPER light enough to wear I just put a tampon in but when I kept taking the tampons out they were still mostly white with lots of brown. Mind you I had cramping on and off all day, around 5pm all bleeding stopped, 10pm I bled again but it was more then spotting it seemed to be a lightish period and I had cramps again. I bled lightish all the way up until 4:30 today. Now from 4:30pm till 12am my time I have a liner on and I had a spot of blood and that’s it from that whole time.. when I wipe there is barely light pink.. I have no idea what this is uhhhh help??😩🙁 PS: usually my flows are SO heavy I bleed out of S+ tampons or am always having to change my tampons more frequently.

Woke up this morning with still nothing except pink when I wipe.
