Do not get up, sit up, move around too much at all before temping. The first thing you should do is stick the thermometer in your mouth.
I use the Walgreen's BBT. It's not the greatest, but I always see my shift.
This. You shouldn't be doing anything before. I use the Vicks therm
I used that one as well, excep tmy last cycle where I tried to use my Walgreen's one. The Walgreens is slow as hell. The Vick's is a fever therm, but it only take 7-8 seconds.
Maybe your Walgreen's BBT battery was dying because mine takes about 15 seconds. Granted, 7-8 seconds has that beat. :-)

This. I use a Rite Aid one, but I wouldn't recommend. It seems like it takes FOREVER for it to beep. I may get a new one.
I use the BD basal thermometer. It is backlit and it saves your last temp for you. Sometimes it can take forever to beep, though.
