OPK advice needed

[littlebird28]

Has anyone ever gotten a false positive with FMU? My brand says nothing about not using FMU, just to not drink or pee for 2-4 hours. This morning was a GLARING positive, but I had a back-up digital test (which says to use FMU) that I used with the same urine- glaring negative! Any insight? Confusled.

It could be possible that the digital has a higher threshold for detecting LH. Other than that I am not sure. If the instructions said nothing about FMU then I would assume you are fine to use it. Maybe test a little later in the evening too and compare. Good luck!

Test again. For me I many times got positives with fmu. Test with a digital this evening and see if it finally turns positive. It may not be as sensitive.

Still negative! I think the FMU was just too concentrated with it. Boo!
