Lingering faint line

13dpo, FMU

When the strip test was processing, the dye just lingered for 1 or 2 seconds in the test line area but then passed over to control line and then got a BFN.

Did this happen to anyone and is it possibly the start of something?

I can't help but think that maybe the hcg level was low for the test area to form a line.

Am i crazy😅?

Ttc for 7+ years have made a few screws loose in my head.
