Trying to pinpoint ovulation

Courtney

Hi everyone! I recently just found out I am pregnant I am around eight weeks and I was just trying to pinpoint when I most likely ovulated.. I took a test on August 1 it was - and two days later on August 3 it was positive is said I was more likely to been ovulating on July 25th which on the 3rd of august would of put me at 9 dpo “if I ovulated that day” and on august 1st when I got my negative 7dpo... just curious if anyone has gotten a positive pregnancy test seven days past ovulation??? If not I think my calculations are correct .
