While Having Sex You Ovulate and Dont Even Know You Do
When are you more probable to conceive?
We're talking about the 'fertile window' – the days in a woman'due south menstrual cycle when pregnancy is possible. The 'fertile window' depends on the length of the menstrual bike, which varies among women.
The 'fertile window' is the day an egg is released from the ovary (ovulation) and the 5 days beforehand. Having sex (intercourse) during this time gives you the best hazard of getting pregnant.

What is an ovulation calculator and how does it help you get significant?
This ovulation estimator or ovulation calendar tin help you lot work out your well-nigh fertile fourth dimension. These are the days you lot are most likely to get meaning.
It can also approximate your due date if you exercise become pregnant during your next fertile days.
Others ways to help y'all work out when you're ovulating:
- Notice changes in vaginal mucus
A few days before ovulation, you may notice your vaginal fungus becomes clear, slick and slippery, and feels a scrap like egg white.
This is a sign that ovulation is about to happen. It's the all-time time to have sex, as sperm travel more hands in this kind of fungus.
- 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 earlier the mean solar day you next wait to ovulate, a positive outcome means you are going to ovulate within the side by side 24 to 36 hours (one to two days).

Facts about timing
Ovulation is when a mature egg is released from the ovary. The egg then moves downward the fallopian tube where it can be 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 only possible if you have sex during the five days before ovulation or on the day of ovulation. But the most fertile days are the three days leading upwards to and including ovulation. Having sexual activity during this fourth dimension gives you lot the best take a chance of getting pregnant.
Past 12-24 hours later on ovulation, a woman is no longer able to get significant during that menstrual cycle because the egg is no longer in the fallopian tube.
There'due south virtually no gamble of getting significant if you have sexual practice earlier or after the fertile window (but if you're not trying to get pregnant, don't rely on this – contraception is your best selection!).

How to know when you're ovulating
Knowing when y'all ovulate can aid yous plan for sex at the right time and meliorate your chance of getting pregnant. Yous can keep track of your menstrual cycles on a chart, in a diary, or on a complimentary period-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the get-go day yous first bleeding (first day of your catamenia). This is day i. The last day of your cycle is the day earlier your next period begins.
- What is a 'menstrual cycle' and a 'catamenia'?
Some people think the 'menstrual cycle' and a 'menses' are the same matter.
A catamenia is when y'all drain (or menstruate).
A menstrual wheel starts on the 24-hour interval when a menses starts (day 1) and ends the twenty-four hours earlier the next menstruation. A cycle'due south length is considered normal if it's between 21 and 35 days. They tin vary betwixt women and from one bike to the side by side.
- Working out your 'average' menstrual bicycle length
If your menstrual cycles are different lengths (most women's cycles are) you can work out your average bike length.
The number of days in a woman's menstrual cycle tin vary calendar month to month. Periods are not always regular. It can be useful to piece of work out an 'boilerplate' bicycle length, based on the length of iii menstrual cycles, to guess when you're nearly probable to be ovulating.
If you add the number of days in iii cycles and divide the total number by three, it gives you lot your boilerplate cycle length.
Example
Sarah tracked her last three menstrual cycles by counting the time from the offset day of 1 period, to the day before the adjacent period.
Cycle 1 was 28 days; Cycle two was 32 days; Cycle 3 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 most fertile days
When you know your boilerplate menstrual bicycle length, you tin piece of work out when you ovulate.
Ovulation happens well-nigh fourteen days before your period starts.
- If your boilerplate menstrual cycle is 28 days, you ovulate effectually day fourteen, and your most fertile days are days 12, 13 and 14.
- If your average menstrual cycle is 35 days ovulation happens around solar day 21 and your most 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 v, vi and seven.
Your most fertile days are the three days leading up to and including the 24-hour interval of ovulation.
Some women have very irregular cycles or observe it difficult to piece of work out an average bicycle length. This can make it difficult to work out when ovulation happens. If it's all as well hard, having sex every two-iii days covers all bases and improves your chance of getting pregnant.
Myth busting
- MYTH
-
A adult female tin can become meaning any time of the month.
- FACT
-
A woman tin merely become significant on a few days during her menstrual bicycle.
Why?
Because eggs and sperm only alive for a short time:
- Sperm alive for around five days.
- Eggs can but be fertilised for around 24 hours (one day) after existence released from the ovary.
Eggs and sperm need to come together at the right fourth dimension for fertilisation to happen to create an embryo.
Getting the timing right
If you lot're trying to get significant, timing is everything. Dr Karin Hammarberg explains how to piece of work out when you are ovulating and the right time to have sex to improve your chance of pregnancy.

What are the chances?
Having sex every bit close as possible to the time of ovulation increases the chance of pregnancy.
If a woman has sex activity six or more than days before she ovulates, the risk she will get pregnant is virtually nothing.
If she has sexual activity five days before she ovulates, her probability of pregnancy is about 10 percentage.
If she has sex on the mean solar day of ovulation, or the two days before, the chance of getting meaning is around 30 percent.
These are average figures and depend on a woman's age.
