13 dpo spotting

lilly

So today I’m 13 dpo, iv had light pink spotting this morning, only when I wiped but not any down the toilet or in my underwear, so I thought I was starting af, however iv had not a drop of blood since, could this be implantation? I had mild cramps yesterday and a bfn test when I was 10 dpo . I’m to scared to test !
