When are you more than likely to conceive?
We're talking near the 'fertile window' – the days in a woman's menstrual cycle when pregnancy is possible. The 'fertile window' depends on the length of the menstrual cycle, which varies among women.
The 'fertile window' is the day an egg is released from the ovary (ovulation) and the five days beforehand. Having sex (intercourse) during this time gives you the best chance of getting pregnant.

Facts almost timing
Ovulation is when a mature egg is released from the ovary. The egg then moves down the fallopian tube where it can exist fertilised. If sperm are in the fallopian tube when the egg is released, there is a good chance that the egg will be fertilised, creating an embryo, which can grow into a baby.
Pregnancy is technically simply possible if you have sex during the five days before ovulation or on the 24-hour interval of ovulation. But the most fertile days are the three days leading up to and including ovulation. Having sex activity during this time gives you lot the best take chances of getting pregnant.
By 12-24 hours afterward ovulation, a woman is no longer able to get pregnant during that menstrual cycle because the egg is no longer in the fallopian tube.

How to know when you're ovulating
Knowing when y'all ovulate can assistance you plan for sexual practice at the right time and improve your gamble of getting pregnant. Yous can keep rails of your menstrual cycles on a chart, in a diary, or on a gratuitous period-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the first day you lot starting time haemorrhage (get-go solar day of your period). This is twenty-four hours i. The last day of your cycle is the solar day earlier your side by side menstruation begins.
- What is a 'menstrual cycle' and a 'catamenia'?
Some people think the 'menstrual cycle' and a 'period' are the same thing.
A period is when you bleed (or menstruate).
A menstrual cycle starts on the solar day when a flow starts (day 1) and ends the day before the next period. A cycle's length is considered normal if it'due south between 21 and 35 days. They can vary betwixt women and from ane cycle to the next.
- Working out your 'average' menstrual cycle length
If your menstrual cycles are different lengths (well-nigh women'due south cycles are) you lot can work out your boilerplate cycle length.
The number of days in a adult female's menstrual cycle can vary month to month. Periods are non always regular. It can be useful to work out an 'boilerplate' wheel length, based on the length of three menstrual cycles, to approximate when you're about likely to be ovulating.
If you add together the number of days in 3 cycles and divide the full number by three, it gives y'all your boilerplate wheel length.
Example
Sarah tracked her last three menstrual cycles by counting the time from the showtime twenty-four hour period of one menstruum, to the day before the next menstruum.
Bicycle one was 28 days; Cycle 2 was 32 days; Bicycle 3 was 27 days
28 + 32 + 27 = 87
87 divided by three = 29
So the average length of Sarah's menstrual cycles is 29 days.
- Working out your virtually fertile days
When you know your boilerplate menstrual cycle length, you can work out when yous ovulate.
Ovulation happens about 14 days before your period starts.
- If your average menstrual cycle is 28 days, y'all ovulate around day 14, and your most fertile days are days 12, 13 and xiv.
- If your average menstrual cycle is 35 days ovulation happens around day 21 and your well-nigh fertile days are days 19,20 and 21.
- If you have shorter cycles, say 21 days, ovulation happens around solar day 7 and your most fertile days are days 5, 6 and 7.
Your nigh fertile days are the three days leading up to and including the day of ovulation.
Some women have very irregular cycles or observe it difficult to work out an average cycle length. This can make it difficult to piece of work out when ovulation happens. If it'southward all too hard, having sex activity every 2-3 days covers all bases and improves your chance of getting pregnant.
Myth busting
- MYTH
-
A woman tin get pregnant any time of the month.
- FACT
-
A adult female can only become pregnant on a few days during her menstrual cycle.
Why?
Considering eggs and sperm only live for a short time:
- Sperm alive for around five days.
- Eggs can only exist fertilised for effectually 24 hours (one twenty-four hours) after beingness released from the ovary.
Eggs and sperm need to come together at the right time for fertilisation to happen to create an embryo.
Getting the timing right
If you're trying to get pregnant, timing is everything. Dr Karin Hammarberg explains how to work out when you are ovulating and the right time to accept sex to improve your chance of pregnancy.

What are the chances?
Having sex as close as possible to the time of ovulation increases the chance of pregnancy.
If a adult female has sexual practice six or more days before she ovulates, the chance she will get pregnant is about zero.
If she has sex five days before she ovulates, her probability of pregnancy is nigh 10 percentage.
If she has sex on the day of ovulation, or the two days earlier, the gamble of getting pregnant is around 30 percent.
These are average figures and depend on a adult female's historic period.
