Wtf 10dpo

So on 6dpo I had very light spotting only when I wiped I’m 10dpo and I still have it sometimes it’s light pink sometimes brown... af is due in 3 days and I’ve been getting negative tests but for the life of me I feel pregnant.... my tests could be faint positive but I’m pretty sure it’s indents what could cause this light of bleeding for so long... my periods always heavy cervix is high and closed btw pic for reference
