TTC digital ovulation test said peak and none peak????


So my husband and I have been trying to conceive our rainbow baby for over a year. I bought those clearblue advanced ovulation tests from Amazon. I bought two boxes of 20 strip tests and used both this morning. One was a peak fertility symbol (happy face)the other was a blank circle. Again I used 2 different tests both clearblue advanced digital ovulation. With the same cup of urine both for 15 seconds. Am I ovulating or not????
