Clearblue confusion

Kaylin

Hi everyone!

As you can see in the pixture, I have done clearblue digital OPKs for the past 6 days. I never got a peak fertility reading and now I am confused. We inseminated on July 21st and we were planning on it again today (until we got a low fertility reading).

One thing is that I used a different reader for my OPK this morning. Could that explain why I went from high to low without getting a peak?
