How to take the BBT?
You can either take your BBT orally or vaginally.

I took mine vaginally the first cycle, this cycle I switched to orally, my temps are eratic no matter which way I take them. I switched to orally taking them when my waking temps were so high. They ranged from 98.4 - 98.6. That made my cover-line 98.7. I thought with the high waking temps that I had a thyroid problem. Doctor even did some blood work. It was just that I didn't know what a big difference it was between the 2. Taking my temps orally they range from 97.4 to 97.9 post Ovulation. Just wanted to let you know so that if you do, dont be surprised if they are high

I've done both. I switched to vaginally about 3 cycles ago. I prefer it, first of all because I have a tendency to sleep with my mouth open, which ruins the accuracy of an oral reading right after you wake up (how do you know if your mouth was open or closed if you were asleep?). Secondly, I saw that my temps tended to CREEP up orally, but vaginally I get a consistently quick reading, usually in about 40 seconds. Plus, you can fall asleep without having the thermometer drop out of your mouth! Much more comfortable too.

When to take the BBT?
Dawn says:
First thing in the morning. Do not move, do not get up to pee, do nothing but pop the thermometer in your mouth or vaginally, if that's your preference.

What if I wake up early?
Add 1/10 of a degree for every half hour that you wake up earlier than your usual time.

What if I wake up late?
Subtract 1/10 of a degree for every half hour that you sleep over your usual time.
