Ovulation help please

EJ

Hi everyone. This is second cycle since iud removal, my period was quite long this time however, I’m showing all the signs of ovulation, a lot of egg white cm and cramping but my ovulation tests are so negative I’ve never seen them so negative before. Last cycle I peaked at cycle day 11. are my cycles just a bit of a mess because of iud removal or should I follow body signs of ovulation and ignore the tests. Any help would be great. Thank you.
