I've never been possibly triphasic!!

I know it doesn't most definitly point to pregnancy, but it still makes me very happy!
I'm trying not to get too excited, though, because this cycle is just weird. FF says I O'ed on CD 22, but it could have also been CD 26, which would blow the triphasic theory.
Usually I have a fairly definite O date, but not this go round. Temps from CD 22 to 26 are just a little too low to be without a doubt post-O, and too high to be pre-O. I think FF might be right on the O date, though, because I have never had temps that high right before O... so that make me think maybe I did O on CD 22 and my temps were just a little lower than normal? The CD 26 theory doesn't show my normal pre-O dip. I always dip pretty low and stay low for several days pre-O.
So... what do the experts think? And when should I test?
ETA: Oh yeah, and I forgot to mention that I have consistantly O'ed between CD 21 and 24 for the past five months, mostly landing on CD 22.
