1. The Temperature Method - How To Keep A Chart:

Mark the date across the top of the Temperature Chart to serve for both Temperature and Mucus Chart, as shown in the example above.
The first day of the period is Day 1 on the chart. Spotting before the period is not counted, it is still part of the previous cycle.
Each day has its own column. Every 7th column is bold to help keep the columns in line on both charts.
Circle the weekends to highlight potential disturbances which often occur at weekends, such as late nights, oversleeping, travelling and alcohol consumption, which may affect readings.
Record the reading for each day with a large dot in the centre of the square opposite the appropriate temperature on the scale. Join the dots up to make a graph. (See later examples)
The rise in temperature after ovulation is actually quite small (only between 0.2°C and 0.6°C on average). Therefore the chart uses half centigrade readings to show the rise more clearly by making it look larger. If, on the small chart above, you had a reading between 37.10 and 37.20, then put the dot in the square marked 37.15. The subdivisions are marked with dotted lines.
