If you start testing your urine a few days earlier the twenty-four hour period you side by side look to ovulate, a positive result means you are going to ovulate within the next 24 to 36 hours (i to 2 days).

• Facts about timing

  Ovulation is when a mature egg is released from the ovary. The egg and then moves down 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 volition be fertilised, creating an embryo, which tin can grow into a baby.

  Pregnancy is technically but possible if you have sexual practice during the five days before ovulation or on the day of ovulation. Simply the near fertile days are the three days leading upwards to and including ovulation. Having sexual practice during this time gives y'all the best adventure of getting pregnant.

  By 12-24 hours after ovulation, a adult female is no longer able to get significant during that menstrual cycle because the egg is no longer in the fallopian tube.

  At that place'south almost no adventure of getting pregnant if you lot have sex earlier or later the fertile window (only if you're non trying to get significant, don't rely on this – contraception is your best selection!).

• How to know when you're ovulating

  To work out the length of your menstrual wheel, record the first twenty-four hour period y'all beginning bleeding (commencement day of your menstruation). This is solar day one. The concluding twenty-four hours of your bicycle is the day before your next menstruation begins.

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

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

  A menstruation is when yous drain (or menstruate).

  A menstrual bike starts on the twenty-four hour period when a period starts (day 1) and ends the twenty-four hours before the next period. A bike's length is considered normal if it'due south between 21 and 35 days. They tin vary between women and from 1 cycle to the adjacent.

• Working out your 'average' menstrual cycle length

  If your menstrual cycles are different lengths (most women'south cycles are) you can work out your average cycle length.

  The number of days in a adult female's menstrual wheel can vary month to month. Periods are not always regular. It can be useful to work out an 'average' bike length, based on the length of three menstrual cycles, to judge when you lot're most likely to be ovulating.

  If you add together the number of days in 3 cycles and carve up the full number by three, it gives you your boilerplate bicycle length.

  Instance

  Sarah tracked her last iii menstrual cycles by counting the time from the get-go 24-hour interval of one period, to the solar day earlier the next period.

  Cycle one was 28 days; Bicycle two was 32 days; Cycle three was 27 days

  28 + 32 + 27 = 87

  87 divided by 3 = 29

  And so the average length of Sarah'due south menstrual cycles is 29 days.

• Working out your most fertile days

  When you know your average menstrual bike length, yous can work out when you ovulate.

  Ovulation happens about 14 days before your catamenia starts.

  • If your average menstrual cycle is 28 days, you ovulate around day fourteen, and your nearly fertile days are days 12, 13 and xiv.
  • If your boilerplate menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.
  • If yous take shorter cycles, say 21 days, ovulation happens effectually twenty-four hours 7 and your almost fertile days are days 5, vi and seven.

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

  Some women have very irregular cycles or find it difficult to work out an average cycle length. This can make it difficult to work out when ovulation happens. If it'southward all too difficult, having sex activity every 2-three days covers all bases and improves your chance of getting pregnant.

Myth busting

MYTH

A woman tin can become pregnant any time of the month.

FACT

A woman can only get significant on a few days during her menstrual cycle.

Why?

• Sperm live for around five days.

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

  If she has sexual activity five days earlier she ovulates, her probability of pregnancy is about 10 per centum.

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