BBT vs. "regular" thermometer

Haven't been using a BBT, just a regular thermometer... wondering how big of a difference there is between the two?

The biggest difference is that bbt's are more accurate, which is better for charting!

What kind of thermometer should I use?

It is important that you use a Basal Body Temperature (BBT) thermometer for accurate fertility charting. If your chart is unclear or unusual, you don't want to wonder whether or not your thermometer is responsible for the ambiguity or unusual pattern. A fever thermometer, even a digital one, is not usually able to give you the sensitivity and precision you need for fertility charting. You need to make sure that your thermometer is a BBT one. It should say BBT, Basal Thermometer, or Fertility Thermometer on the package.You can find a BBT thermometer at most well-stocked pharmacies and drugstores. We recommend using a digital BBT thermometer for ease of use, but a mercury BBT thermometer will also work.

FWIW, i used a regualar thermometer when conceiving #1... it seemed to work okay. However, I am using a BBT this time. My temps are so much more erratic. sigh.

My Temperatures are so rocky and erratic. What can be causing this? What can I do about it?

If your temperatures are erratic, the first thing you should do is review the guidelines about taking your BBT and make sure you are using a special basal body temperature thermometer. If you are following the guidelines (taking your temperature at the same time each morning, before getting up and using a BBT thermometer) and still have erratic temperatures, the first thing to do is review your data to see what could be disturbing the temperature. You may also consider changing your thermometer or replacing the battery in your thermometer to see if this helps. You may also want to talk to a Fertility Friend guide to get her opinion about what could be causing the erratic temperatures. Some women who are unable to get a clear pattern when taking an oral temperature are able to get a clearer pattern when they take their temperature vaginally. If you have several cycles that are erratic and you are taking and recording your BBT properly, and you are unable to see an ovulation pattern, you should talk to your healthcare provider.
