Ovulation?

So the first day of my last period was July 7. It lasted 5 days. My cycle runs 30-34 days. I got a faint positive on August 3 rd. Which would be 10 DpO if I went off of glows prediction. The only other time my husband and I could have conceived was 5 days after my period ended so I would have been 19 dpo on August 3rd if that’s when I ovulated . Do you think I ovulated that week or 21-26 and got faint positives until my period was actually a week late last week? Or do you think I ovulated 5 days after my period ended?
