Dpo and opk?

Lovely • IG: Plentifully.day TTC #4. Sept 2014 tubal reversal. Feb 2016 HSG: blocked tubes. May 2016 IVF: failed. Aug 2016 BFP turned to 4th loss

Maybe I've been counting wrong? I took opk Nov 9 and it was positive so do I start counting that day or the day after?

Also i know you're supposed to stop testing after the first positive but I'm a rebel and kept testing and got more positives two days after that, should I count that at all?
