Timing of Ovulation

The length of your luteal phase determines your time of ovulation. The length of this phase will almost always remain constant from one cycle to another. The average length for most women is 14 days. For some women the length of this phase can vary between 10-16 days, but will almost always stay at that particular length for each consecutive cycle.

To calculate when ovulation occurs within your cycle simply subtract the length of your luteal phase from the overall length of your cycle as shown in the diagram below. Alternatively you might like to make use of our Free Online Ovulation Calculator or purchase our ovulation and pregnancy calendar from our online shop.

28-14 = 14. Ovulation occurs Day 14
32 –14 = 18 Ovulation occurs Day 18
32 – 10 = 20 Ovulation occurs Day 20
