OPKs and FMU?

i know they say not to use them with FMU, but what do you all think??

this morning i got one that is borderline positive. then tonight i took one and got barely a line. but i also had LOTS of water this afternoon so im going to test again in a few hours (yes i know, im completely obsessed)..

anyway what do you all think? im mad cause i do have digitals and i forgot i had them and didnt take one this morning when i should have..

Re: OPKs and FMU?

I've gotten positives with both a digital and the line kind with FMU as well as mid day so I think it depends. I'm very regular so I pretty much know when I'm about to O.
