First signal evap or positive ?

Mariha

Hello everyone, I took a pg test this morning but I got a faint line. It was after the 3 min window like around 4 or 5 min because I timed it. I am 9dpo (0vulate late)

and AF is due on the 19 but my temp went down to from 98.6 to 98.3 for 3 days. Do you think it's positive? Isn't my temp supposed to stay elevated? Please help. Thank you
