Implantation? Confused!! Help!

Rissa • Married to the love of my life, TTC #2! We have a beautiful 8 yr old!
So I took a few HPT and I had one come back with a faint positive but then I started bleeding pretty heavy and its continued for the last 6 days. AF wasn't due until Jan 6th could this be implantation bleeding? AF was just here Dec 6-10th....
