What kind of thermometer?

I have heard that i need to use a themometer that which shows like 98.99 d format. I also hear that target brand is good.

ANy one has any suggessions?

What you are looking for is specifically called a "basal body thermometer."

I don't have one so I am hoping others give you some suggestions for brands - they're all prob. equally good as long as you make sure it is a basal body thermometer and says so on the package.

I think any brand is fine. My is the drug store brand, and its simple and easy to use
