Not knowing is driving me mad! Would love to hear how long it was after implantation bleed you got a positive test?

I had a little bit of light brown spotting on Friday which I am hopeful was implantation bleeding as I have no idea what else it would be. It’s now Tuesday and no period and a negative test. I have never had spotting without a period before and don’t know if I should be getting my hopes up or not! Negative test and no period! Any experiences of this?
