How is the luteal phase counted? What if I have spotting before my period starts?
The luteal phase of the menstrual cycle is counted from the day after ovulation (ie the day of your first raised temperature) through to and including the day before your next period starts. Remember that your period starts with the first day of actual bleeding, so any days of spotting beforehand are counted as part of the luteal phase.
