Ovulation test help!!

Katie • Married to my wonderful husband! Mommy to our sweet 2.5 yr old boy. TTC #2!
So the other morning I took 2 ovulation tests with the same FMU. Clear blue digital came back with a solid smiley (peak) and first response came back with pale line. I have since tested with first response test only and they are both have no lines. It's early for me to ovulate according to my calendar but just wondering if it's possible that I actually did ovulate and the first response was incorrect the first time. Any advice is greatly appreciated!!
