BBT ?!?

Question

Ok ladies I just went and bought a bbt thermometer. 
It says to be like "half awake" to take temp. No talking no moving to smoking no drinks, take it right away first thing same time everytime (or very close)... 
It also says to start taking it on first day of menses. Does it have to be or can I start doing it tomorrow morning when I do an opk? My opk says start day 16 and today is day 16. Thanks ladies

Answer

Start charting whenever! Put the thermometer right on the nightstand, and set an alarm. I like to set two alarms on my phone: the first one wakes me up and I take my temperature. The second one is just in case I fall asleep with the thermometer in my mouth :) A bbt thermometer can take up to five minutes to get your temp exactly right, so it's better to be safe than sorry and have your alarms spaced 5 minutes apart.

Start good luck !
