Digital OPK positive - negative strips

I got peak on the clearblue digital OPK in the morning and didn't get a positive on the OPK test strips until 24 hours later (also fmu). Which should I go by? I thought digital was supposed to be less sensitive.

    This is probably too late now, but thought I’d throw in my 2 cents in case you or someone else has the same issue in the future.

    I won’t sugar-coat it, I don’t trust the clear blue digitals. In my experience they don’t match other OPKs or even each other.

    At one point I actually had two different boxes of clear blue digital advanced. I test the same sample of urine using each one. One said I was at my peak fertility- solid smiley! ....the other said I was not fertile - open circle! Which was it??

    I go by just the cheap strips now - at least they are consistent.

    I used two vials so both 'peaks' were covered. Maybe the strips are better, I do like being able to see the line darken until positive.

    Going by clearblue I inseminated at 16 hours and 36.28 past peak.
    And going by test strips, I inseminated at 8 hours and 24.28 hours past peak.
