Did I ovulate?

Sarah

I think I totally missed out this month! I’ve been using clearblue advanced ovulation tests and been getting high fertility results for the past 2 days this morning included (using fmu) . I’m waiting anxiously for the peak fertility so I tested in middle of the day today and got a low fertility result. Has this happened to anyone else? Can this be bc I tested in middle of the day and my urine might not be greatly concentrated?
