How does the Fertility Calculator work?

This tool helps you determine when you might be ovulating based on information from your most recent period and the length of your cycle. This is an approximate date, and the calculation assumes a regular menstrual cycle. Should your cycle be irregular, you may want to try other ways to pinpoint ovulation, such as monitoring your basal body temperature and cervical mucus.
