One possible indicator is that the menstrual cycle is regular and consistent in flow.It is also possible for some people to ovulate before menarche, meaning pregnancy could occur before any menstruation has occurred.The average age of menarche is more obvious than the age of ovulation, so most studies look at this age rather than that of ovulation.
