Two peak readings? Thoughts please 🙏🏻

Ka

I use both the Clearblue advanced digital OPK and the easy@home strips. I had gotten blank smileys from CD 10-13 then on CD 14 I got a peak smiley! No flashing smileys. Today I retested with the digital at CD 16 since the 48 hrs was up and I had gotten another positive easy@home. Another peak smiley reading! What does that mean? With how dark my easy@home OPK test was CD 15 AM, is Clearblue wrong?
