Comparing results of regular and advanced digital OPKs

I started using advanced digital OPK on Day 6 and got blank circle (low fertility). Day 7 I got flashing smiley (high fertility) and have had the same result through Day 12. I'm TTC via IUI procedure so I can't keep having procedures in the hopes that the next day I'll get the solid smiley (peak).

So, today I got the 'regular' digital OPK and tested with both the regular and advanced to compare results. Regular (pink) = Smiley; Advanced (purple) = flashing smiley. I'm confused. Am I at "peak" aka ovulating, or what? The six days of flashing smileys is really breaking my optimism that this product works.
