1 Work out the length of your average menstrual cycle. Day one is the first day of the menstrual period and the last day is the day before the next period begins.  Ovulation happens about two weeks before the next expected period. So if your average menstrual cycle is 28 days, you ovulate around day 14.
Your new assistant at work probably shouldn't know when you're ovulating. Mark the first day of your period and count 28 days from then. Highlight that 28th day as when you'll probably be starting your next period. The 28-day cycle isn't exact for everyone, of course. Maybe you're a 29- or 30-dayer. Indicate when you actually do get your period on your cycle tracker, too. After a few months, you'll see a pretty regular pattern, ditch that 28-day mark, and go with the amount of time that works for you.
