I'm new to charting and after reading Taking Control of Your Fertility, I decided to take the plunge and go for glass instead of digital. My biggest concern was shaking the thing down, since that was mentioned over and over in the reviews. However, I have unlocked the secret (thanks to some Googling).
To Shake Down Thermometer Sans Carpal Tunnel
1.) Select a sock (clean, sturdy, no holes in the toes, preferably missing its partner so it can be dedicated to the following procedure).
2.) Insert the thermometer metal tip down into the sock (i.e. the part that goes in your mouth is at the toe of the sock - see why it should be clean?)
3.) Stand clear of furniture and swing the sock clockwise for 10-15 seconds - careful not to hit yourself (i.e. the spin should be horizontal, like a wall clock's hands, not horizontal like a record spinning)
4.) Remove shaken down thermometer
The only con to this thermometer is the fact it takes 5 minutes to read. However, it's accurate and that's its purpose - sometimes we get so caught up in our fast food nation mentality that we want everything INSTANT and NOW even if it means we sacrifice quality. Charting is about getting in tune with your body - your body's natural state is NOT fast forward. So, slow down, stick this baby under your tongue and charts away!
