Whenever I am online I constantly have my FF chart up too...I can't stop staring at it...just in case there is something new on it, that might tell me something I didn't already know!!!
Yp I do that too - when I'm waiting for ov I watch it hoping FF will put the crosshairs onto it; and when I'm in the 2ww keep eatching for FF to put a BFP on there (all without me inputting any data )
