Mary,

Yours is the first message I've seen in a long while.  Personally, I use sympto thermal, although technically, not now, b/c I am nursing my 2.5 y/o DD and my 7 m/o DS. 

Mostly, I frequent Mary's NFP message board at Delphi Forums.  Have you been there?  There are both sympto thermal users there and mucus-only NFPer's, and it's a wonderful source of support.
