Why Not FMU When Using OPK'S
Does anyone know why FMU shouldn't be used when using OPK's?
I have used both FMU and late afternoon. FMU is just easier bc I can't hold it for 4 hours during the day-I'll pop!!
TIA

Re: Why Not FMU When Using OPK'S

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.

The monitor is not only detecting your LH surge, but estrogen as well.

Thanks for posting this.
the funny thing is the first month I used OPK's (November) I religiously tested in the late afternoon and I was never really sure if I got a positive reading bc the test line was never really dark.
BUT in December (on Xmas eve as a matter of fact) I used FMU and the test line was screaming purple. It was super positive.
Ah well I guess it doesn't matter bc it didn't "take" in the end 
Thanks again
