When after implantation cramps/ bleeding did you get a BFP?

Hey all. We only BD twice this cycle and it was on the 17th and 24th (Sept.).  I believe I ovulated either on the 22nd or the 23rd, but I could be wrong. AF isn't due until the 8th, so I'm 5 days away. all tests have been coming back negative. Yesterday all day I had dull aches cramps, which never happens for me until during AF. I'm crossing my fingers that this was implantation. My questions is; how long after implantation cramps or bleeding, did y'all get your BFP
