Just did some research and I guess I may have answered my own question. Thought I would share if anyone was still curious. Any more input of personal experience would be great still though.
Q: What time of day should I test?
A: The best time to test is 2 p.m., or as close as possible. Anytime between noon and 8 p.m. is fine, first morning urine is not recommended. The reason for this is that most women experience a surge in the morning, but it can take 4 hours for it to show up in your urine.
Make sure to test at about the same time every day.
Q: On what day of my cycle should I start testing?
A: If you have a variable cycle, you should use the date of your shortest cycle in the past six months as a starting time.
