| Re: BBt
The first few months I charted, I used a reg. digital thermometer that I bought at the Dollar General store for $3.99. It worked fine for me and gave me a clear O. I finally found a bbt at cvs...it's a cvs brand digital bbt therm. So that's what I've been using this month. I really can't tell much of a difference in my charts now that I'm using a bbt.
As the previous poster said, there are sites online that sell them, you should be able to find one by searching. Good luck!!
