Implantation bleeding

Hi guys I'm new on this app so was kinda hoping for a lil advice ..

I started bleeding earlier today so I put a pad on thinking my period was coming I'm due on in two days ... I've been having a small amount of discharge with streaks of blood in it .... I done a home pregnancy test a couple days ago and it was negative but the bleeding has now stopped so I'm confused.

Any advice please and thanks :)
