Ovulation is when a mature egg is released from the ovary. The egg then moves down the fallopian tube where it tin be fertilised.

- What is a 'menstrual cycle' and a 'menstruation'?
Some people think the 'menstrual cycle' and a 'menstruum' are the same thing.

- Working out your 'boilerplate' menstrual cycle length
If your menstrual cycles are different lengths (most women's cycles are) you can work out your average cycle length.
The number of days in a woman'due south menstrual bike can vary calendar month to month. Periods are not ever regular. It tin can be useful to work out an 'average' bike length, based on the length of 3 menstrual cycles, to judge when you're almost likely to be ovulating.
If yous add the number of days in three cycles and divide the full number by three, it gives you your average bicycle length.
Example
Sarah tracked her last three menstrual cycles by counting the time from the first twenty-four hour period of one period, to the mean solar day before the adjacent menstruum.
Cycle 1 was 28 days; Cycle 2 was 32 days; Cycle iii was 27 days
28 + 32 + 27 = 87
87 divided by three = 29
So the average length of Sarah's menstrual cycles is 29 days.

Ovulation happens near xiv days earlier your period starts.
- If your average menstrual cycle is 28 days, y'all ovulate effectually day 14, and your nearly fertile days are days 12, xiii and fourteen.
- If your average menstrual wheel is 35 days ovulation happens effectually twenty-four hours 21 and your almost fertile days are days 19,20 and 21.
- If you have shorter cycles, say 21 days, ovulation happens around day 7 and your most fertile days are days v, six and 7.
Your most fertile days are the three days leading up to and including the day of ovulation.
Some women accept very irregular cycles or find it difficult to piece of work out an boilerplate bike length. This tin make it hard to piece of work out when ovulation happens. If it's all as well difficult, having sex every 2-3 days covers all bases and improves your chance of getting pregnant.
