Implantation?

Abigail

If someone does have implantation bleeding, how long should you wait to test after that?

I don't know when I ovulate or when my period will come (irregular periods) but I'm on cycle day 53. I had a little spotting on cycle day 47. Just when I wiped 2 times.

I've got symptoms but negative tests so far. Anyone know when it might be positive if that was implantation bleeding?
