The rhythm method. That's about the only other completely natural way I know of. If you are very regular, you can track your cycle and can figure out exactly where in your cycle you are ovulating.

The rhythm method is not good at all because it is a rare woman that falls into a 28 day regular cycle ... It's the Natural Family Planning Method that is actually EXTREMELY reliable because it is a daily tracking of ~ basal body temperature, cervical mucus, cervical position, etc. ... IF you actually track these they will always and consistently pinpoint ovulation. Even those with regular cycles can have annovulatory cycles or ovulate early/late ... which cannot be predicted with the simple rhythm method even in regular cycle women.

Check out Toni Wechsler's "Taking Charge of Your Fertility" ... it is the most comprehensive, easy to understand book out there on this subject. I believe it should be mandatory reading for every single woman. My oldest daughter will be reading it this summer (it's her required reading!) :)
