OPK help please

Hi everyone!

I'm attempting to do o+12 this month but I'm having real trouble with OPKs. The clear blue digital are giving me nothing but flashing smileys and the cheap ones aren't giving me a line darker than the test. I have watery and not a lot of CM so not much to go off there (presuming it's down to the shops?). Really want to pin point O but I'm so confused, I'm usually the same time every month so I'm panicking that I've missed it!

I can't recommend O+12 as a sway tactic but it's your sway your way. just be sure you ahve ONLY one attempt, not more than one

I would wait for solid smiley regardless of what the other ones are doing and then have one attempt 48 hours after that.

BE prepared for lots and lots of BFN.
