Cycle and ovulation
Basal body temperature rises by around 0.3°C after ovulation because of progesterone, and stays higher until the next period. Charting confirms ovulation has happened in retrospect but cannot predict it in advance, so it is more useful for understanding your pattern than for timing sex.
