Irregular cycles are not necessarily bad, for example during menstruation this can be normal because it takes time for your body to get into a regular pattern. In general however irregular cycles mean irregular ovulation, this is a major indicator of health because your body will only delay or prevent ovulation if it thinks you cannot cope with pregnancy, or it will only occur if you have some sort of health problem effecting your cycles.
