How long for a positive result?

So on the 6th to the 8th of this month I had what I thought was implantation bleeding, I had pink/reddish brown/brown spotting every time I used the toilet along with slight cramping. I know it wasn't my period because it had no flow to it and the cramps were no way near as painful as my usual period cramps are. My period was due on the 12th of this month but I still haven't got it, I've taken two pregnancy tests (one on Tuesday, one on Friday) and they are negative. I guess I'm just looking for a tiny fraction of hope here, did anyone get a positive result later on then they expected to get one?

It's just heartbreaking seeing negatives all the time and then reading stories about the lucky ladies who have gotten positive results at like 8dpo. Please someone give me some hope lol 👏🏽🙈
