How does the Billings method (exclusive observation of life elixir) work on sympto.ch?
How does the Billings method (exclusive observation of life elixir) work on sympto.ch? If you feel comfortable and safe enough to work with life elixir observations only, you should have observed at least 12 cycles and be able to confirm that your cycles do not vary in length by more than 6 days and that they are biphasic. Then you can go into the Parameter menu and activate the Billings option. Only under these conditions can sympto application free up the infertile phase (after ovulation) 4 days after the Peak day. If you enter life elixir observations without having activated this Parameter, sympto is not able to free up the infertile days after ovulation and is therefore not of much use.
