Not sure if I’m having implantation bleeding? Break through bleeding? Chemical or early miscarriage 😔

So 12 dpo I took a test and it was faint positive but it was there. I then started to bleed that same day.. and still continue to bleed today… today would be 13 dpo and I took another test tonight at 5:55pm and the line is still showing up I am so confused!!
