What counts as FMU?

[JennaW]

Ok, I'm not totally dense, let me be more specific.  I am pregnant and DH put one of those "Intelligender" tests in my stocking, just for fun.  I plan on taking it tomorrow.  You are supposed to use FMU.  The thing is I have to get up to pee so many times a night. Seriously, sometimes it is like every 2-3 hours.  So I am trying to figure out if there is a certain amount of time you have to "hold it" for it to count as FMU in these circumstances.

Thank you!

I've heard 4 hours, and I've heard that your hormones are highest between 2 and 6.  I don't know anything about that particular test.
