One of the most common questions you’ll hear when you’re pregnant is, “When are you due? But like most questions about life and about children, the answer is usually more complicated than that. Our language about due dates reflects our need for things to be on time. Even the baby is considered “early” or “late. But because most due dates bills, library books are deadlines, we tend to project that framework onto birth. People who tell their family and friends a due date may have to endure 50 calls a day asking, “is the baby here YET? But babies are not library books–no one’s going to charge your baby an overdue fine.
Why a IVF Due Date Calculator is important
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”.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Physicians at the Women’s Institute perform over embryo transfer procedures every year. Implantation is essential for successful ART and IVF procedures, and many interventions have been studied to possibly improve implantation rates and thus pregnancy and live birth rates. Endometrial activation is one such intervention, sometimes referred to as endometrial “activation” or “scratch,” and it is defined as “intentional endometrial injury, such as endometrial biopsy or curettage, in women undergoing ART”.
A previous study found that implantation rates, clinical pregnancy rates, and live birth rates were more than twofold higher in women who underwent endometrial biopsy in the cycle before subsequent IVF treatment. Another study which examines endometrial activation prior to IVF similarly has concluded that endometrial activation prior to the embryo transfer cycle significantly improves clinical pregnancy rates and live birth rates in women undergoing ART. Although the type of endometrial procedure is not specified, the timing activation was found be most effective when performed in the cycle prior to the embryo transfer.
The mechanism of increase endometrial receptivity is still unknown; however three proposed hypothesis exist. The first hypothesis proposes that local activation of the endometrium induces endometrial decidualization which increases the probability of embryo implantation. The second hypothesis is that endometrial healing following endometrial activation increases secreted cytokines, interleukins, growth factors, macrophages, and dendritic cells which are beneficial to embryo implantation.
The final hypothesis suggests that endometrial maturation is abnormally advanced during ovarian stimulation, so endometrial activation may lead to better synchronicity between the endometrium and the embryo.. Endometrial activation has been found to have clear benefit in pregnancy and live birth rates in a previous study, however no uniform technique has been determined. The objective of this study is to compare two types of endometrial disruption – a vigorous endometrial biopsy with a Pipelle curette and a four quadrant endometrial “scratch” using a Shepard insemination catheter – to determine if the live birth rates are equivalent for the two methods.

Refer to the text below the tool for more information about determining due dates following in vitro fertilization treatments. In the case of an IVF pregnancy, the start dates are planned and scheduled, so known in advance.
A frozen embryo transfer FET cycle means thawing one or more embryos frozen during a previous treatment cycle and transferring that embryo or embryos to the uterus in order to try to establish a pregnancy. The process is a routine procedure at Life Fertility Clinic. When ovaries are stimulated in a typical IVF or ICSI cycle, they produce multiple eggs for insemination and this often leads to a number of healthy embryos being created. As only one or two will be transferred to the uterus immediately, the rest can be frozen to use in another IVF cycle if the first transfer does not result in a pregnancy, or at a later time to create a sibling.
Occasionally a woman having IVF treatment will be advised to freeze all her embryos and not to transfer any immediately if the lining of the uterus has not developed to a suitable stage or if she is at risk of developing ovarian hyper-stimulation syndrome OHSS. Freezing embryos is also a potential avenue for a woman who wants to postpone pregnancy until her late 30s or early 40s but who understands she may not have suitable eggs of her own by then.
Some embryos or possibly all embryos will not survive the freezing and thawing process if cells are damaged.

Infertility is a far more common problem than most people realize. Fortunately, at The Center for Assisted Reproduction, or CARE Fertility, we offer a range of fertility treatments to help patients overcome fertility issues so they can experience the joys of pregnancy and parenthood. One of the most successful fertility treatments is IVF. IVF, or in vitro fertilization, assists throughout the reproductive process to maximize the chance of a successful pregnancy.
singleton births conceived via In Vitro Fertilization (IVF) with transfer dates occurring between January 1, and December 31,. Only the first singleton.
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. Primarily, this is because the moment of conception is hidden. Some studies say days or 40 weeks is the best guess for a due date. Other studies say days or 40 weeks and 2 days is better. Due dates are complicated. Sometimes in a non-IVF conceived pregnancy , due dates are adjusted or changed. Usually, your doctor will closely monitor the pregnancy for a while to be sure the fetus is developing as expected.
Calculating Your IVF Due Date
If you did IVF, you may wonder if your due date is more accurate than it otherwise would have been. After all, you know exactly when the eggs were retrieved and when the embryo was transferred. Is your baby more likely to be born on the exact due date because you did IVF? The estimated due date EDD is more of a ballpark — hardly anyone delivers on their exact due date. If anything, IVF babies are more likely to be born sooner. But it does mean your due date is less likely to be changed as your pregnancy progresses.

Whether you are trying to conceive on your own or undergoing fertility treatment the two week wait can seem like an eternity. This is the time between suspected ovulation — or in the case of those undergoing fertility treatment, the time of insemination or transfer — and when the first pregnancy test can be taken resulting in reliable results. To help navigate the curiosity and unknowns, we gathered some question from our community, ran them by our nurse educators, and came up with answers to your most pressing two week wait questions.
This period of time is referred to as the two week wait. The blood test — officially called a beta hCG blood test — detects hCG and is the most accurate indication of pregnancy. Traces of the administered hCG may still be in your bloodstream and detectable by a test even if implantation has not occurred. A false negative might occur as a low level of hCG may be undetectable in a urine test despite a pregnancy starting as these are less sensitive than the blood hormone tests we administer.
On average, two weeks after your IUI or embryo transfer you will come back to our Center for your pregnancy test. Your body has been through a lot and the medications you have taken are designed to promote the optimal environment for pregnancy. You may experience some cramping, spotting or light bleeding, abdominal bloating, fatigue, and breast tenderness. While you may be slightly alarmed to experience some of these symptoms, they are normal and do not signify that you are or are not pregnant.

The first child conceived by IVF was Louise Joy Brown, and since her birth, seventy-five percent of women who have undergone this procedure have become mothers of healthy, happy babies. This procedure has an overall fifty-five percent birth rate. In vitro fertilization was first successfully achieved in the s, when Dr. Walter Heape, of Cambridge, UK, managed to transplant a fertilized ovum into a rabbit. The idea of IVF was not seriously discussed in humans until , when two Harvard researchers published a paper suggesting it could be viable.

After all the items on your IVF checklist are complete, your fertility coordinator will send in your prescription, and create a calendar that outlines the individual stimulation protocol developed by your physician.
The calendar dating is based on your menstrual cycle start, and includes a schedule of medications and appointments for your IVF cycle. We want to provide you with the best chance for success and part of this process is injection training. During the injection class you will participate in a hands-on injection technique demonstration. This is part of your checklist.
If your protocol includes an ultrasound, the sonographer or provider will measure your uterine lining and check your ovaries for any follicles or possible cysts.
