I thought for ovulation tests the best time was mid day like 10-5 but I just read my easy@home tests instructions and it says anytime is fine
My fertility clinic told me to test at the same time everyday and to choose a time between noon and 4pm for best results.
Morning would be right when you wake up and need to go to the bathroom, evening would be after dinner when you gotta go to the bathroom before going to bed take another test. That's when I tested, it was never at the same time everyday, just before eating when I wake up and after dinner before sleeping If you use the lines tests I suggest getting the "Premom" app you can put pictures into the app and it'll help show when you ovulate and if the test is high or low but you gotta be sure to put certain brands into certain spots in the app
