This might sound *unprofessional* lol but judging by the fact that your pee is still super wet in your specimen window, it looks really fresh. If I saw that before 10 min I would definitely think that might be positive and retest again the next day.
i say it's positive. i got my first positive at 10 DPO when I found out i was pregnant with my little girl, and it was super light like that and i used the dollar tree brand test as well. test in another couple of days
