By the way, as a comparison, here's my chart on fertilityfriend. I just started my period today :-( and you can see how my temp just dropped below the coverline this morning.

OK, I see! Well, in that case, I would think your coverline would be maybe 96.1 or so. By the way, that's a nice rise!!! And yes, if you do get a low temperature around the time your period is due, it's probably just around the corner :-( Hopefully, you won't have that, though :-)
