What Needs to Be Done Before Baby Arrives

When are you more likely to conceive?

Nosotros're talking nigh 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 5 days beforehand. Having sex (intercourse) during this time gives y'all the best take a chance of getting pregnant.

Ovulation Calculator

• What is an ovulation calculator and how does it assist you get pregnant?

  This ovulation estimator or ovulation calendar can aid you work out your about fertile time. These are the days you are most likely to get meaning.

  Information technology can also estimate your due engagement if y'all do go significant during your adjacent fertile days.

  Others ways to help you 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 scrap similar egg white.

  This is a sign that ovulation is nigh to happen. It's the best time to have sexual practice, equally sperm travel more than hands in this kind of mucus.

• Use an ovulation predictor kit

  You can use a predictor kit from a supermarket or pharmacy, to exam your urine for signs of ovulation. If yous offset testing your urine a few days before the day y'all next expect to ovulate, a positive result ways yous are going to ovulate within the adjacent 24 to 36 hours (one to two days).

• Facts about timing

  Ovulation is when a mature egg is released from the ovary. The egg and 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 exist fertilised, creating an embryo, which tin 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 up to and including ovulation. Having sex during this time gives y'all the best hazard of getting meaning.

  By 12-24 hours after 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's virtually no chance of getting pregnant if you lot have sex earlier or subsequently the fertile window (simply if you're not 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 tin help you program for sex at the correct time and improve your take a chance of getting pregnant.  You can keep runway of your menstrual cycles on a nautical chart, in a diary, or on a free period-tracker app on your smartphone.

  To work out the length of your menstrual wheel, record the offset day you commencement bleeding (first day of your menstruum). This is twenty-four hours ane. The last 24-hour interval of your bike is the mean solar day earlier your side by side period begins.

• What is a 'menstrual cycle' and a 'catamenia'?

  Some people think the 'menstrual bike' and a 'flow' are the same thing.

  A period is when you lot bleed (or menstruate).

  A menstrual cycle starts on the day when a menstruation starts (day ane) and ends the day before the side by side period. A bicycle's length is considered normal if information technology's between 21 and 35 days. They can vary between women and from ane cycle to the next.

• Working out your 'average' menstrual cycle length

  If your menstrual cycles are dissimilar lengths (well-nigh women's cycles are) y'all tin can piece of work out your average cycle length.

  The number of days in a woman's menstrual cycle tin can vary month to calendar month. Periods are not always regular. It can be useful to work out an 'boilerplate' wheel length, based on the length of three menstrual cycles, to judge when yous're most likely to be ovulating.

  If yous add the number of days in three cycles and split up the full number by 3, information technology gives yous your average cycle length.

  Example

  Sarah tracked her terminal three menstrual cycles past counting the time from the first day of one period, to the day earlier the adjacent period.

  Cycle one was 28 days; Wheel two was 32 days; Cycle three 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 about fertile days

  When y'all know your average menstrual cycle length, you lot tin work out when y'all ovulate.

  Ovulation happens about xiv days before your catamenia starts.

  • If your average menstrual bicycle is 28 days, you ovulate around day 14, 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 virtually 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 5, 6 and seven.

  Your most fertile days are the three days leading up to and including the day of ovulation.

  Some women accept very irregular cycles or discover it difficult to piece of work out an average bike length. This tin make it hard to work out when ovulation happens. If information technology's all too hard, having sex every ii-three days covers all bases and improves your adventure of getting pregnant.

Myth busting

MYTH

A woman can get significant any time of the month.

FACT

A woman tin only go 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 but be fertilised for effectually 24 hours (one solar day) afterwards beingness released from the ovary.

Eggs and sperm demand to come together at the right time for fertilisation to happen to create an embryo.

Getting the timing right

If yous're trying to get pregnant, 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 as close every bit possible to the time of ovulation increases the chance of pregnancy.

  If a woman has sexual activity vi or more days before she ovulates, the hazard she will get meaning is virtually zero.

  If she has sex activity 5 days before she ovulates, her probability of pregnancy is about 10 pct.

  If she has sex on the twenty-four hour period of ovulation, or the ii days before, the chance of getting meaning is around xxx percent.

  These are average figures and depend on a woman's age.
