Ovulation cycle can be calculated various ways: either by starting with the first day of the last menstrual period (LMP), by measuring basal body temperature, or other methods. There are a number of apps that enable you to track your cycle easily, but these apps are less helpful if your period is irregular.
For those of you who love input: the first part of the ovulation cycle is called the follicular phase. The second phase of the cycle is called the luteal phase and is from the day of ovulation until the next period begins.
