Ava assesses your chart for a biphasic pattern starting from six days after the estimated ovulation date (6 days post predicted ovulation date).

Ava needs to have gathered enough data in a given cycle in order to accurately assess its pattern (try not to miss more than three nights per cycle).

It is possible to observe one or more “rises” of parameters early in your cycle before the shift reported in literature occurs. This is why Ava delays informing users of a biphasic parameter pattern until several days after ovulation.
