Just when I thought I got the hang of taking BBT, I am now totally confused. I bought a second BBT thermometer during a trip since I forgot to pack one. So now I have 2 BBT thermometers, same brand. This morning, I used the 2 to take my temp consecutively....and they were different. 97.54 and 97.64. Now which is the right BBT? So I tried using two to take the temp at the same time ... tried this three time one after the other and I got: thermometer A: 97.58, 97.46, 97.50 and thermometer B: 97.43, 97.43, 97.58. THis is oral temp.
WTF? How can I trust my charting skills now??
