AF or implantation?

I'm so confused. It's 3 days before I was expecting AF, no symptoms besides swollen breasts. I was dreaming that I took a HPT and could vividly see that it was positive. I woke up because I felt something wet between my legs. I went to the bathroom and there was brownish red blood, not like my normal period. At first I thought maybe this was the famous implantation bleeding I keep hearing about. I sat on the toilet for a while both sad and confused. I wiped again and this time it was really bloody. Is it too soon to take a HPT if it is implantation bleeding?
