Thermometer

[zechal]

Hi everyone, I'm new here, but not so new to Fam I suppose. My husband and I have been ttc since July with no luck. Originally I purchased "Taking Charge of Your Fertility" and just paid attention to my cervical mucus, as my husband and I were wanting it to "just happen". But I've decided I wanted to start tracking my temperature as well. My question is I often have several days where my temperature is 97.2 in a row. When I look at the charts in the book, it appears that individuals temps vary by a tenth most days. So I'm wondering if I should get a new thermometer, mine is just a digital one.

Recommendations?
