How soon after implantation did you test positive?

I’m 5/6 days from period. Had some light pink spotting and cramping today. Usually wouldn’t spot this early so I’m not sure if it’s implantation or AF is just being weird this month.

I didn’t track bbt. I know my LH peak was the 12th. I’m honestly just curious about others experiences. Please be kind. It took us two years for our first. And now trying for our second I’ve already had a loss. So as I say often trying to conceive is a tough and emotional journey.
