Too hydrated?

Took a test 2 days before AF. Didn't know I was supposed to take first thing in the morning... It's my first time. However my urine had no color. I drank 6 glasses of lemon water, grand iced tea and two cups of green today and took the test at 4:30pm and got a BFN. Should I try again? Or am I just kidding myself. Need advice please.
