Super duper faint lines at 13, maybe 12 DPO

Has anyone had such faint lines just a day before AF is due and everything be okay? The latest I’ve gotten my first faint line has been 11 DPO. But now I’m near certain I’m 13 DPO (OPKs on medicated cycles) and I just got this. I tested two days ago and nothing. Just so worried, as they’re barely noticeable (but my wife saw them, so yay!). I’d think it’d be so much darker by now. I’ve never had such faint lines so late. I’m just so tired of chemicals and this Antiphospholipid Syndrome BS. I want for this to be a healthy little bean…
