What Days Am I Most Likely to Get Pregnant
When are you more likely to conceive?
We're talking virtually the 'fertile window' – the days in a adult female's menstrual cycle when pregnancy is possible. The 'fertile window' depends on the length of the menstrual bicycle, which varies amidst women.
The 'fertile window' is the twenty-four hour period an egg is released from the ovary (ovulation) and the 5 days beforehand. Having sex (intercourse) during this time gives you the best chance of getting pregnant.

What is an ovulation computer and how does it help you become pregnant?
This ovulation calculator or ovulation agenda tin help y'all work out your nearly fertile time. These are the days yous are most likely to get meaning.
Information technology can as well estimate your due date if you practice get significant during your next fertile days.
Others means to help you piece of work out when you lot're ovulating:
- Notice changes in vaginal mucus
A few days before ovulation, you may notice your vaginal mucus becomes articulate, slick and slippery, and feels a bit similar egg white.
This is a sign that ovulation is about to happen. Information technology's the best fourth dimension to have sex, as sperm travel more easily in this kind of mucus.
- Use an ovulation predictor kit
You tin use a predictor kit from a supermarket or pharmacy, to test your urine for signs of ovulation. If you start testing your urine a few days before the day y'all next wait to ovulate, a positive issue means you are going to ovulate inside the adjacent 24 to 36 hours (i to ii days).

Facts about timing
Ovulation is when a mature egg is released from the ovary. The egg then moves downwards the fallopian tube where it can be fertilised. If sperm are in the fallopian tube when the egg is released, there is a good run a risk that the egg will exist fertilised, creating an embryo, which can grow into a infant.
Pregnancy is technically only possible if you take sex during the five days before ovulation or on the mean solar day of ovulation. But the most fertile days are the iii days leading up to and including ovulation. Having sex during this time gives you the best hazard 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.
There'south almost no run a risk of getting pregnant if y'all have sex before or after the fertile window (but if you're non trying to get pregnant, don't rely on this – contraception is your best option!).

How to know when you're ovulating
Knowing when you ovulate can help you programme for sex at the correct time and improve your chance of getting pregnant. You tin can keep track of your menstrual cycles on a chart, in a diary, or on a free catamenia-tracker app on your smartphone.
To work out the length of your menstrual wheel, record the kickoff day you start bleeding (outset mean solar day of your period). This is day 1. The last mean solar day of your wheel is the twenty-four hour period before your next period begins.
- What is a 'menstrual bike' and a 'period'?
Some people think the 'menstrual cycle' and a 'period' are the same thing.
A period is when you drain (or menstruate).
A menstrual cycle starts on the twenty-four hour period when a menstruum starts (day ane) and ends the day before the next period. A cycle's length is considered normal if information technology's between 21 and 35 days. They tin can vary betwixt women and from i cycle to the next.
- Working out your 'average' menstrual cycle length
If your menstrual cycles are different lengths (most women's cycles are) you tin work out your average cycle length.
The number of days in a woman'south menstrual cycle can vary month to calendar month. Periods are non always regular. It tin be useful to piece of work out an 'average' bike length, based on the length of three menstrual cycles, to estimate when you're most likely to be ovulating.
If yous add together the number of days in iii cycles and divide the total number by three, it gives you your boilerplate cycle length.
Example
Sarah tracked her terminal iii menstrual cycles by counting the time from the first twenty-four hour period of one period, to the day before the next period.
Cycle 1 was 28 days; Cycle 2 was 32 days; Cycle iii was 27 days
28 + 32 + 27 = 87
87 divided by three = 29
And so the average length of Sarah's menstrual cycles is 29 days.
- Working out your nigh fertile days
When yous know your average menstrual wheel length, you tin can work out when yous ovulate.
Ovulation happens about 14 days before your catamenia starts.
- If your average menstrual cycle is 28 days, you ovulate around day 14, and your virtually fertile days are days 12, xiii and 14.
- If your boilerplate menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,twenty and 21.
- If you have shorter cycles, say 21 days, ovulation happens around 24-hour interval 7 and your most fertile days are days 5, 6 and 7.
Your about fertile days are the three days leading up to and including the mean solar day of ovulation.
Some women have very irregular cycles or observe it difficult to work out an average wheel length. This can make it hard to work out when ovulation happens. If it'southward all too hard, having sex every 2-3 days covers all bases and improves your chance of getting pregnant.
Myth busting
- MYTH
-
A woman can get pregnant any time of the calendar month.
- FACT
-
A woman tin can only get meaning on a few days during her menstrual bicycle.
Why?
Because eggs and sperm only live for a curt time:
- Sperm live for around five days.
- Eggs can but be fertilised for around 24 hours (one day) afterwards being 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 meaning, timing is everything. Dr Karin Hammarberg explains how to piece of work out when y'all are ovulating and the right fourth dimension to have sex to better your gamble of pregnancy.

What are the chances?
Having sexual activity equally close as possible to the time of ovulation increases the chance of pregnancy.
If a adult female has sex half-dozen or more days before she ovulates, the run a risk she will get meaning is virtually zippo.
If she has sex 5 days earlier she ovulates, her probability of pregnancy is nigh 10 percent.
If she has sex on the day of ovulation, or the two days before, the chance of getting significant is around 30 percentage.
These are average figures and depend on a woman's age.
When does preconception health brainstorm?
Professor Sarah Robertson, Director of Robinson Research Institute, University of Adelaide, highlights the key time earlier pregnancy that your health is most important to ensure your child has the best start to life.
