Should I remove temperature spikes or dips from my chart?
If you have an occasional temperature spike or dip that obviously does not fit the pattern of your other temperatures, you can remove these from your fertility chart. This will help to make interpreting your chart easier. Try to only remove dips or spikes that vary from your usual temperature range by 0.3℃ or more.
To remove a single spike or dip – paper fertility chart:
1) Erase the temperature which gives the spike or dip
2) Join the temperatures on either side of the misfitting temperature with a dotted line
