How much or As far as I know, no. You can track or look after a regularity of an ovulation, taking rectal temperature in the mornings during all cycle. It is possible to learn to notice an ovulation, observing for change of viscosity and quantity or amount vydeleny. Often at anovulatory cycles monthly come in time.
