It’s best to test with second wee of the day or the same time each day, the instructions for the ovulation tests I’ve used suggests not to use the first morning pee and to test 2-3 times a day when close to ovulation for best chances of catching your peak
Did you continue testing after your low peak last cycle? Because you may not have ovulated yet. I had a very similar situation last cycle where I thought I missed it on CD13 because then it got lower only to get a proper peak much later on CD22. So keep testing just incase
Looks like your peak is still yet to come perhaps! Keep testing 💗
