Tiffany, I'm not goot at chart analyzing at all but I'll give it a shot. Maybe FF hasn't given you cross hairs yet because there aren't enough temps in there yet? Try putting in some dummy temps for the days leading up to the day you ovulated.
Or it could be that the supporting information that you provided (cm and cervial position) don't add up to O?
Totally guessing as usual.
As for the VIP membership to FF? I liked the VIP membership but the only reason was because with VIP you can use their message boards! Which I really liked. HOwever, if you're using it just for charting, I personally didn't think it was worth paying for .......but that's just my opinion
good luck Tiffany!
