Facts nigh timing
Ovulation is when a mature egg is released from the ovary. The egg then moves down the fallopian tube where information technology can be fertilised. If sperm are in the fallopian tube when the egg is released, there is a skilful take chances that the egg will be fertilised, creating an embryo, which can abound into a babe.
Pregnancy is technically only possible if y'all have sex during the five days earlier ovulation or on the 24-hour interval of ovulation. But the most fertile days are the three days leading upwards to and including ovulation. Having sex during this fourth dimension gives yous the best gamble of getting pregnant.
By 12-24 hours later on ovulation, a adult female is no longer able to become significant during that menstrual cycle because the egg is no longer in the fallopian tube.

How to know when you're ovulating
Knowing when you ovulate can help you program for sex at the right time and improve your chance of getting significant. You can keep track of your menstrual cycles on a chart, in a diary, or on a gratis flow-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the first day yous starting time haemorrhage (showtime twenty-four hours of your catamenia). This is day 1. The terminal day of your bicycle is the day before your next period begins.
- What is a 'menstrual cycle' and a 'period'?
Some people retrieve the 'menstrual bike' and a 'period' are the same thing.
A period is when you drain (or menstruate).
A menstrual cycle starts on the day when a period starts (twenty-four hours 1) and ends the twenty-four hours earlier the side by side menstruum. A cycle's length is considered normal if it'southward between 21 and 35 days. They can vary betwixt women and from one bicycle to the next.
- Working out your 'average' menstrual cycle length
If your menstrual cycles are different lengths (most women's cycles are) you tin piece of work out your boilerplate bike length.
The number of days in a woman's menstrual cycle can vary month to month. Periods are not always regular. Information technology can be useful to work out an 'average' bicycle length, based on the length of 3 menstrual cycles, to judge when you're well-nigh likely to be ovulating.
If y'all add the number of days in 3 cycles and divide the total number by three, it gives you your average cycle length.
Case
Sarah tracked her last three menstrual cycles past counting the time from the first solar day of one flow, to the day before the next period.
Cycle 1 was 28 days; Cycle 2 was 32 days; Bike iii was 27 days
28 + 32 + 27 = 87
87 divided by 3 = 29
So the average length of Sarah's menstrual cycles is 29 days.
- Working out your most fertile days
When you know your average menstrual cycle length, you lot tin work out when you ovulate.
Ovulation happens almost 14 days before your period starts.
- If your average menstrual cycle is 28 days, y'all ovulate around twenty-four hour period 14, and your almost fertile days are days 12, 13 and fourteen.
- If your average menstrual cycle is 35 days ovulation happens around mean solar day 21 and your about fertile days are days xix,20 and 21.
- If you lot have shorter cycles, say 21 days, ovulation happens effectually mean solar day 7 and your near fertile days are days five, 6 and vii.
Your most fertile days are the 3 days leading up to and including the day of ovulation.
Some women have very irregular cycles or find information technology difficult to work out an average cycle length. This can make it hard to work out when ovulation happens. If information technology'due south all too hard, having sex every 2-3 days covers all bases and improves your risk of getting pregnant.
