Methods for Estimating the Due Date
Most pregnancies last around 40 weeks or 38 weeks from conception , so typically the best way to estimate your due date is to count 40 weeks, or days, from the first day of your last menstrual period LMP. Another way to do it is to subtract three months from the first day of your last period and add seven days. So if your last period started on April 11, you’d count back three months to January 11 and then add seven days, which means your due date would be January Calculating your due date based on the first day of your last period works well for women who have a relatively regular menstrual cycle.

Each cycle of FET, like that of the other ART procedures, involves multiple steps, occurring at a specific time during a four-week period. An approximate timetable and overview are presented below. If you have been pregnant, or if it has been more than one year since your last embryo transfer, a repeat uterine measurement should be performed before FET.
If you have never had an evaluation of the uterine cavity or if it has been longer than a year or if you have risk factors for uterine structural abnormalities, we will recommend a uterine cavity evaluation prior to FET, either with a saline infusion sonohystogram, office hysteroscopy or a hysterosalpingogram. Monitoring of follicle development is often performed during a FET cycle by using transvaginal sonography.

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.
When an IVF pregnancy is confirmed, patients are eager to determine when their baby is likely to be born. Since IVF is different than a traditional pregnancy, the due date can be calculated based on the date of egg retrieval or transfer. Our fertility specialists are happy to assist with calculating your IVF due date after treatment at our Dallas, TX fertility clinic. A typical pregnancy lasts 40 weeks, or day. When a woman conceives naturally, doctors determine the estimated due date based on the first day of the last menstrual cycle.
This method is used because most people do not know exactly when they ovulate. A woman with a regular day menstrual cycle typically ovulates on day However, ovulation can actually occur earlier or later than this date, so a due date is only a rough estimation of when the baby is likely to be born. Women who undergo IVF do know exactly when they ovulated, so it is more accurate to calculate a due date following IVF treatment.
Below is a brief explanation of the two basic methods for calculating your IVF due date:.

It is common to be given a single ‘estimated due date’ EDD which corresponds the point at which it is estimated that your pregnancy will have lasted 40 weeks. It may be more helpful to be prepared for you baby arrive some time after 37 weeks, and to focus on 42 weeks as the time by which you have a good chance of having given birth. Many women with longer pregnancies find that everyone is asking whether they have had their baby yet, and that health care workers start to suggest inducing labour.
For some women this will be the right decision, but it is important to know that this is your decision to make. Charting temperature, monitoring mucus, using ovulation test kits and knowing times when you could have conceived, or having conceived by IVF may mean you have your own information about when you became pregnant. There is a tendency for midwives and doctors to talk as though the EDD written in your maternity notes is something definite, rather than an estimate which may or may not be accurate.
In that case, if the EDD is later than it should be that could mean that the birth is delayed unnecessarily. This suggests that in general ultrasound dating is more accurate in predicting the birth date than counting from the last monthly period 1,2 but it is still only an estimate and may not always be accurate. A recent study 3 of women who conceived by IVF and therefore knew when their egg was fertilised, found that the routine ultrasound dating scan consistently put their estimated birth date earlier than it should have been by an average of 3 days.
