How does the pure temperature method work on sympto?
The characteristic temperature rise shows the passage of ovulation. The rise is the proof that ovulation has taken place and will not happen again in this cycle. Without the observation of elixir, more days need to be considered as fertile for safety reasons. The temperature option requires a 4th and 5th temperature rise, sometimes even a 6th value, before freeing up the phase of postovulatory infertility. Furthermore, this option does not exempt you from your elixir observations, as your elixir flow may happen to start very early, i.e. before the Döring/Rötzer day, and make you fertile from that moment on. On the other hand, the temperature method also works for irregular cycles.
