I have read several places not to test OPK with your 1st morning urine. It is ok to have liquids before you test but not too much since it will dilute your urine. You are not supposed to urinate for 4 hours before you do a test. I have read to test between mid-morning and early evening for best results.
Hey, this is a quote from peeonastick.com that may help you:
"10. Should I use first morning urine (FMU) with OPK's? No. LH is synthesized early in the day, and is not metabolized into your urine until later. So, as a rule, you are more likely to catch your surge later in the day. ("They" say you should test sometime around 2-4 p.m., but I've had fine luck at 10 p.m.-midnight.) Using FMU may not be a problem for you, but if you do not detect a surge during the cycle you use FMU, try testing later during the next cycle.
Note: the Clearblue Fertility Monitor is the exception. The FM Monitor does require FMU. "
