Is this normal? Any help is appreciated!

Got a positive pregnancy test day. It’s faint but it’s there and it’s not an indent. 12 dpo. Now I’m spotting a little when I wipe. Very light brown/yellow. I’m freaking out. AF is predicted in two days. Am I having a chemical?

I’m just so worried. This is the first time I got a positive test since my miscarriage in August. I so badly want this to be my rainbow baby.
