Evap Line or positive? Checked way after the time limit.

Hey everyone! So I took a clinical guard test after work yesterday (at 11/12 dpo - 8 hour hold) but after collecting my sample I noticed my typical pre-AF spotting (AF is due tomorrow or Saturday) so I threw the test out after ~60-90 seconds because what’s the point? About 4-5 hours later I used the bathroom again and for some reason decided to pull out the test and WTF!! (See attached pic). Can I just discount this as an Evap Line since it was so many hours after? I also dug up my tests from 2-3 days ago to compare but they are still stark white BFNs! I’m going to try and test again after work but wanted your opinions! Thank you!

P.S sorry about all the fuzz on that test, I kept it wrapped in my robe pocket because I had already told DH we were out this cycle!
