Ovulation test at night?

Shannon
Has anyone taken an ovulation test around 6:00pm? I have never taken one before and I tarted hurting on my right side pretty bad so I wanted to test the theory and see if that meant I was really ovulating. So I went and bought the ovulation kit and it said I was ovulation. I did ready the directions and it said the morning pee would be the best but that I could do it as long as I haven't drank that much. So I didn't drink anything for about three hours and I took the test and it said I was ovulation. My question is, could that have been a false result since I took it so late in the day?
