So I was looking into this brown blood mixed with cm that I had last night and this morning. I hope that this is my case but here is a neat article I found.

What I thought was neat was the fact that the article said that you can usually get a accurate HPT result around the implantation so that made me realize that you can have hcg before implantation. Now I am off to find out how long the fertilzed egg is in your uterus before it actually implants (since they say that you don't produce hcg until the egg makes it to the uterus.
eta: okay, this site sayst that the fertilized egg will float in the uterus for a few days before it implants. Haven't found any exact number of days yet though. (last bullet under week 3)
