Possibly pregnant? (Pic in comments)

Yari

My husband and I took a break this month after our miscarriage in Feb.... AF was due yesterday and thought, “what the hell” and tested this morning.... I feel like it should be darker at this point in my cycle, plus I’ve never seen a test line fade in and out....what do you think? Invalid?

I should note, this was not FMU... it was after a 10 Min wait.
