I used clearblue advanced digital ovulation tests. This morning I used a new holder from the package I just bought. Using my first morning urine the test said peak fertility. I used the holder from my previous package of tests around 4 hours later and it said high fertility. I did drink a good amount of water since getting up this morning. Do I go with the first test that said peak? The top test is from this morning. The bottom was later in the day.
