How soon after implantation bleeding can you get a positive test result?

Ca

My period was four days late today, and then today I’ve been experiencing what I’m pretty sure is light implantation bleeding. First it was darkish brown, and now it’s light pink.

How soon after you had implantation bleeding is it possible to get a positive?

Could I test right now?

I’ve been having such terrible nausea recently :( I just want to find out ASAP
