Also it is daytime now, you've been (unless you are a nightshift worker) up for awhile. Your temperatures will be much higher than your basal body temps. That's why you are supposed to take your temps first thing in the morning, before you even get out of bed. The slightest movements can throw your temps for a loop. This could explain the variances in the temperatures you just took too. ;)
I know. Both sets of temps were taken around 1 in the afternoon, not for NFP purposes but for "is my thermometer broken?" purposes. :)

I'm surprised your thermometer has a 'hundredths place... most don't!
Either way - the fluctuation is ~0.2degF orally and ~0.1degF vaginally in your little experiment... really, in the grand scheme of things, this isn't that bad. When you chart your temperature you're looking for an elevation at a particular time. You take your temperature through phase 1 & 2 just to establish a baseline - it doesn't have to be perfect. You know WHEN your temperature should start to rise (when your mucous and cervical position signs start trending away from fertile after ovulation), and that temperature rise should be AT LEAST 0.4degF and sustained for AT LEAST 3 days... rarely, have my sustained elevated temperatures been JUST 0.4degF - usually they range up to ~0.8degF. So my point is that this fluctuation (~0.1-0.2degF) is just in the noise... you should still be able to detect a significant temperature rise correlating with your other signs to ensure that you're safely into the infertile luteal phase...
VERY helpful to know that my thermometer goes to a greater level of detail than most, and that a .14 fluctuation isn't a big deal. :) I went through my old charts (2006-2007) and you're right--usually my ovulation was marked by 0.4 - 0.8 temperature increases, which means a .14 fluctuation isn't a big deal. Whew! I am going to stick with vaginal temps since it seemed a little more consistent and I won't have to worry about keeping it in the perfect position in my mouth, etc. I'll report back if I have more problems! :)
