My RE told me never to test for OPK with FMU because it can give a false positive. That could be what happened, since you got those mixed test results?

I heard the same thing, except that it was true only for the strip tests, not the digital ones. When I spoke w/ Clear Blue, they advised that for the purposes of their test (yes the OPK digital test) to use FMU. This is what it says on their web site:

"To make sure that the hormone level in your urine is concentrated enough for the test to detect, itâ??s important not to urinate for at least 4 hours before doing the test.You can test at any time of the day, but it should be at the same time each day. Many women find that first thing in the morning is the most convenient."

Since posting this, I have had a faint headache all day and felt pinching/cramping in my lower abdomen (on the R side) so i'm almost convinced I am O-ing right now.

Just to be on the safe side, i'm going to continue testing. :) I totally agreed w/ what you said, until I talked to ClearBlue directly.
