False positive
I took a test this morning after my longest sleep and it was negative. Then, took one this afternoon and it was High Fertility. I know you're supposed to only take it once until it's high, so would this make it false? Or since I already tested in the morning, is it accurate?

Estrogen is produced while you sleep therefore you should use the first urine passed after your longest period of sleep for reliable results. I fyou have seen High Fertility later in the day you can still rely on this result, High fertility will be displayed until Peak fertility is detected.
