When did you got BFP after implantation bleeding?

I got IB 4 days before my period is due. I really believe it is IB, first time in my life such type of bleeding just a very light brownish blood it lasted for 3 days on and off and during i wipe whenever i pee. I did not use napkin as it is very small amount of blood.

I tested after 2 days but Bfn. Then i tested again today and it’s already 7 days ago but bfn still. Am I out already?

Anyone experience the same and got Positive pregnancy test?

Ps. Im 3 days late of my period.

Thanks ladies
