I have been using OPKs all month, and I usually use FMU because I drink a lot of water throughout the day. Actually, I shouldn't say I use FMU because I always wake up in the middle of the night to use the bathroom. The last few days, when I use FMU, my result is +, but it's never + in the evening. I haven't had a rise in my chart yet. Could this be a false +?

Re: OPK and FMU
I'd always heard you aren't supposed to test with FMU.
ETA: Maybe the water is diluting the PM test too much.

Can you link us to your chart?
It could be a false +, it could be that your urine is diluted in the evenings. What kind of OPK are you using?

Depends on the OPK. CBE Digitals say to test whenever you'd like. I got my + with FMU yesterday.
You should have at least 4 hours of undiluted urine in your bladder when you test.
