TTC & SPOTTING AROUND AF

So I’m TTC since a while now, 13 DPO I started spotting blood, 14 DPO I DID Fill almost half panty liner (just thought my AF arrived), I am 15 DPO today and still spotting, there are no other symptoms of AF other than spotting. Never had a period that is this light. Anyone has any idea what might be going on?? Feel like this isn’t implantation either.. if anyone has experienced the same thing otherwise. I bleed a little pink with lots of white CM, bleed a little reddish.. but it seems so much watery..!!! NOT USUAL FOR ME.. ANYONE CAN PLEASE HELP ME FIGURE OUT WHAT IT MUST BE.. IT WOULD BE OF GREAT HELP.. my anxiety is going through the roof.. also i might add that i do spot one day prior to AF, but its 3 days in a row now.. NEED ANSWERS 😔😔
