Can You Find Out the Sex of the Baby at 14 Weeks

When are you lot more probable to conceive?

Nosotros'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 cycle, which varies amidst 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 fourth dimension gives you lot the best chance of getting pregnant.

Ovulation Calculator

• What is an ovulation calculator and how does it help y'all get pregnant?

  This ovulation calculator or ovulation agenda tin help yous work out your well-nigh fertile time. These are the days yous are nearly probable to get meaning.

  Information technology tin can besides estimate your due appointment if you do become significant during your next fertile days.

  Others ways to help you work out when you're ovulating:

• Notice changes in vaginal fungus

  A few days before ovulation, you lot may notice your vaginal mucus becomes clear, slick and slippery, and feels a bit similar egg white.

  This is a sign that ovulation is about to happen. It'due south the best time to have sex, as sperm travel more easily in this kind of mucus.

• Use an ovulation predictor kit

  You can utilise a predictor kit from a supermarket or pharmacy, to test your urine for signs of ovulation. If you starting time testing your urine a few days earlier the 24-hour interval you next wait to ovulate, a positive issue means you are going to ovulate within the next 24 to 36 hours (one to ii days).

• Facts about timing

  Ovulation is when a mature egg is released from the ovary. The egg and so moves down the fallopian tube where it can exist fertilised. If sperm are in the fallopian tube when the egg is released, at that place is a good take a chance that the egg will exist fertilised, creating an embryo, which tin can grow into a baby.

  Pregnancy is technically simply possible if you 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 up to and including ovulation. Having sex during this fourth dimension gives you the best gamble of getting pregnant.

  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.

  In that location's almost no hazard of getting pregnant if you have sex before or after the fertile window (but if you're not trying to get significant, don't rely on this – contraception is your all-time option!).

• How to know when you're ovulating

  Knowing when you ovulate can help you plan for sex at the correct fourth dimension and better your take a chance of getting pregnant.  You can keep track of your menstrual cycles on a nautical chart, in a diary, or on a complimentary period-tracker app on your smartphone.

  To piece of work out the length of your menstrual cycle, record the first day you start bleeding (first 24-hour interval of your period). This is day ane. The last day of your cycle is the twenty-four hour period before your side by side menstruum begins.

• What is a 'menstrual wheel' and a 'period'?

  Some people think the 'menstrual bicycle' and a 'menses' are the same affair.

  A flow is when you bleed (or menstruate).

  A menstrual cycle starts on the day when a catamenia starts (mean solar day 1) and ends the 24-hour interval earlier the side by side period. A cycle'south length is considered normal if information technology'due south betwixt 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 can work out your average cycle length.

  The number of days in a adult female's menstrual bike can vary month to month. Periods are not e'er regular. It can be useful to piece of work out an 'average' bicycle length, based on the length of three menstrual cycles, to estimate when yous're most probable to exist ovulating.

  If you add together the number of days in iii cycles and split up the full number by three, information technology gives you your average bike length.

  Instance

  Sarah tracked her terminal three menstrual cycles by counting the time from the first twenty-four hours of ane menstruum, to the 24-hour interval before the next period.

  Bicycle ane was 28 days; Cycle 2 was 32 days; Cycle iii was 27 days

  28 + 32 + 27 = 87

  87 divided by 3 = 29

  And then the average length of Sarah's menstrual cycles is 29 days.

• Working out your about fertile days

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

  Ovulation happens about 14 days before your period starts.

  • If your average menstrual cycle is 28 days, you ovulate around day 14, and your near fertile days are days 12, 13 and 14.
  • If your boilerplate menstrual cycle is 35 days ovulation happens around twenty-four hours 21 and your most fertile days are days 19,twenty and 21.
  • If you have shorter cycles, say 21 days, ovulation happens around day 7 and your most fertile days are days v, 6 and 7.

  Your most fertile days are the 3 days leading upwardly to and including the mean solar day of ovulation.

  Some women accept very irregular cycles or detect it hard to work out an average cycle length. This tin make it hard to work out when ovulation happens. If it's all too hard, having sexual practice every 2-3 days covers all bases and improves your chance of getting pregnant.

Myth busting

MYTH

A woman can get meaning any fourth dimension of the month.

FACT

A woman tin can merely get meaning on a few days during her menstrual cycle.

Why?

Considering eggs and sperm simply live for a brusque time:

• Sperm live for around five days.
• Eggs can only be fertilised for effectually 24 hours (one solar day) after being released from the ovary.

Eggs and sperm need to come together at the right time for fecundation 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 yous are ovulating and the right time to have sexual activity to improve your adventure of pregnancy.

• What are the chances?

  Having sex every bit close as possible to the fourth dimension of ovulation increases the risk of pregnancy.

  If a woman has sexual activity 6 or more than days earlier she ovulates, the take a chance she will get pregnant is virtually zero.

  If she has sex activity v days before she ovulates, her probability of pregnancy is most 10 percent.

  If she has sex on the day of ovulation, or the two days earlier, the adventure of getting pregnant is around 30 percent.

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