OPKs confusing

Has anyone every gotten a consistent line, but not a positive or high or peak line with second morning urine on OPKs, but little to no line later in the day (even on a four hour hold)? If this has happened to you, what ended up happening?

I’m currently 7+ days late for my normal ovulation so just not trusting the tests or my body. I’m also BBTing so I know I haven’t missed ovulation as there’s no hint of biphasic or even one teams above my cover line.

(Pic attached of SMU now like this for 4 days) yesterday texted three times later in the days, some where barely squinters.
