Basal body temp thermometer

Hi,

We are TTC. I am using a thermometer that reads the degrees to the 100th degree (97.25, 97.49, etc). But I recently read that a reading to the 100th degree is not necessary and all we need is a thermometer that reads to the tenth degree (97.2, 97.4). Which do you use? I bought my thermometer a year ago. I used it consistently for a while, stopped for a while, now I'm using it again while undergoing fertility treatments. Because its a year old, I don't know if it's accurate and am wondering if I should get a new one, and which one to get. Thanks in advance!

Do you need it?  No, but it does make things much easier.  Without that extra place value, your chart will look flat/even.  For example, 97.22 will be charted as 97.2 just like 97.29 would be charted as 97.2.

This.

FWIW, I have used both types and never had a problem confirming O in the 1.5 years I charted.
