Ovulation test

Nicole

Hey guys so I have been using clear blue digital ovulation tests. I ran out though and I did get a flashing smiley face this morning but not a solid smile but I ran out and got first response ovulation test. I'm confused as to why clearvlue said to use fmu and others say afternoon. But anyways what do you think about this test would you say close to ovulation? Don't have any other first response ones to compare it too
