Faint Positive hpt 5 days after "period"

Sorry this will be a long post and probably much tmi just a warning!!

So my last period was on the 17th of June it was only 1 day and super light. But I tested and bfn so I went on testing with ovulation test to see when I ovulated I had a positive on June 27th bd on the 26th. I thought for sure I was going to get pregnant timing was perfect. Tested day before af and bfn. Af came on July 11 and ended 15th it wasn't heavy and it didn't have clots but I thought I was out for that month for sure. A few days later I started crying for nothing (well really because I wanted to sleep but couldn't) anyway this was 5days after my period and it was a faint positive showed up within time limit actually at the 2min. Any advice would be helpful.
