App says ovulation is today....

Brittney

I'm going to add two pictures of test 14, 15, and 16 and 17 today, my test are darker in the mornings, I do not use first mornings pee, I pee in the morning then I want two hours later without eating and drinking anything. But I was experimenting with the test, I would do first morning pee but the test looked weird.... I just dont know what to go by? Also I test the same times everyday and the test get lighter in the afternoon and at night... so any help with the test for today please? These two were with the same pee
