Can They Be Trusted?
"I would stay with what you have been using. If you want to change, I would change after this cylce. I won't change in the middle, that could really throw things off." - Jen
"I don't think an ear thermometer is going to be accurate enough for charting purposes. Heck - even a digital fever thermometer isn't recommended. If you are going to chart, I would purchase a Basal Body Temperature (BBT) thermometer. You can find them at Target, WalMart, pharmacies, etc. and are less than $10. They are normally with the thermometers or with the birth control (condoms, etc) section. They measure down to the 10th degree of accuracy and that is what you need for tracking your charts." - Julie
"I don't like using the ear thermometer on my daughter because I've been told it isn't reliable. I'd say stick with the BBTherm." - Susan
