How many days should you wait to test?

My period is 3 days late. On the 22nd in the evening I had brown discharge when I wiped accompanied by slight cramps.

How many days after possible implantation will you show up negative? My cervix is very high, soft and closed. I took a pregnancy test today both negative. It wasn’t my first morning pee tho.
