I am so sorry. Yes, that is a huge reason I do the temps, just to know where the heck I am sometimes. Plus, I usually know from my temps, before I can even test, that AF is coming because they start to dip. So, it's a nice early warning.
I really don't know but, if it is day 1, then you'll really know by tomorrow, right? So I say wait and see what tomorrow brings... if you know what I mean!
