Anyone think I have a chance

I'm 9dpo today took this test this morning maybe a line I don't know it's early bbt chart posted below. I had my 21 day taken yesterday I OVULATED the day of my temp spike I had the same single rusty brown spot on my underwear at 7dpo when waking up as I did with my first pregnancy back in January I'm wondering the chances of getting a real positive in a few days.
