Who knows a lot about implantation bleeding??

Ha

I had what I think was implantation bleeding 8 and 9 DPO. Lasted 2 full days (AF normally 4) and it was just this light brown/pink CM-like texture, only had it when wiping, never enough to even get on my panties. Never turned into actual blood at all.

So my question is...When will my test show up positive if I am pregnant? My period is officially late (I’m 13 DPO) but HCG tests all negative so far.
