However, you can figure out your due date yourself, if you want. The average gestation for a singleton pregnancy is generally considered to be days or 40 weeks from your last menstrual period. However, due dates are more complicated and less certain than that. Also, due dates after infertility or after IVF can be a little different, too. Only 5 out of babies are born on their assigned due date. Studies have found that ovulation can occur a few days off from what a positive ovulation test or BBT chart indicates. Also, implantation of the embryo also varies.
Ultrasound Reference Chart Based on IVF Dates to Estimate Gestational Age at 6–9 weeks’ Gestation
Accurate determination of gestational age underpins good obstetric care. The Monash Chart, but none of the existing charts, accurately determined gestational age among an independent IVF twin cohort twin pairs. We conclude that commonly used ultrasound reference charts have inaccuracies. We have generated a CRL reference chart based on true gestational age in an IVF cohort that can accurately determine gestational age at 6—9 weeks of gestation.
Accurate dating of gestational age is central to good obstetric care.

Women hoping to have a baby through fertility treatment can from today use an online calculator to show them how likely they are to succeed. IVF in-vitro fertilisation is expensive, only sometimes available on the NHS and less successful than many people think. The calculator, available for free at ivfpredict. Up until now, estimates of success have not been reliable. To use the calculator, nine questions must be answered. It will ask the woman’s age, how many years she has been trying to get pregnant, what doctors say is the cause of her infertility, what previous IVF attempts she has made and what were the outcomes.
Debbie Lawlor, professor of epidemiology at the University of Bristol, said the calculator would be of use not only to couples but also to “healthcare funders like the NHS to ensure appropriate use of resources”. It raises the possibility that GP consortia could turn couples down for NHS treatment on the basis that their chances of success are too low. The findings, which are published in the Public Library of Science , were welcomed by Professor Gordon Smith, head of the department of obstetrics and gynaecology at Cambridge University.
It is a great resource.

All you really need to know or be able to provide is the start date. Due dates are always based on a specific start date plus a number of weeks usually, 38 weeks.

Normal cycle. During each menstrual cycle, a woman’s ovaries release an egg. This process is called ovulation. The follicle develops into a corpus luteum, which can produce and release estrogen and progesterone for a specific period, i. To continue to produce these hormones, the corpus luteum needs to be triggered by another hormone called “human chorionic gonadotropin” HCG.
As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date .
Because the human egg is capable of fertilization for only 12 to 24 hours after ovulation the date of ovulation may be taken as being the date of conception. However, ultrasound determination of the date of ovulation has the same imprecision as does the ultrasound estimate of the gestational age and, therefore, a precise date of conception cannot usually be determined as with in vitro fertilization. In addition, although a woman is most likely to become pregnant if she has sex on the day of ovulation conception may also occur from live sperm still in her reproductive tract on the day of ovulation if she had sex for up to five days before ovulation [26,27].
The due date may be estimated by adding days 9 months and 7 days to the first day of the last menstrual period LMP. This is the method used by “pregnancy wheels”. The accuracy of the EDD derived by this method depends on accurate recall by the mother, assumes regular 28 day cycles, and that ovulation and conception occurs on day 14 of the cycle. Use of the LMP to establish the due date may overestimate the duration of the pregnancy, and can be subject to an error of more than 2 weeks .
In cases where the date of conception is known precisely, such as with in vitro fertilization, the EDD is calculated by adding days to the date of conception. Ultrasound uses the size of the fetus to determine the gestational age the time elapsed since the the first day of the last menstrual period. The accuracy of the ultrasound estimate of the gestational age varies according to the gestational age. The Society of Obstetricians and Gynaecologists of Canada recommends the earliest ultrasound with a crown rump length equivalent to at least 7 weeks or 10 mm should be used to determine the gestational age .
