Many women like a visual method to see the fertility date in chart. The following chart would definitely help:
Ovulation is the event that defines the phases of the menstrual cycle. The phase before ovulation, when the ovarian follicles are developing, is called the follicular phase. The phase after ovulation is called the luteal phase. The length of the follicular phase may vary but the luteal phase length is generally constant from cycle to cycle for the same woman, lasting 10-16 days. When cycles are irregular, it is usually because ovulation occurred earlier or later than usual. Knowing when ovulation occurred allows you to see if intercourse was well-timed for conception and lets you determine your luteal phase length. Knowing your luteal phase length tells you when to expect your period or a positive pregnancy test result.
The fertility chart below illustrates the cycle phases with ovulation indicated by the vertical red line.
