Implantation? Please help.

Chrissy

I didn’t track my baby dances, BUT I did put in there when I possibly had implantation bleeding? It only lasted the two days and was dark brown only when I wiped and I was crampy and had other period-like symptoms.

I took a pregnancy test late last night and it was negative.

I’m 7 months postpartum right now.

When will there be enough HCG to show a positive if I am?

Thanks!
