If you've recently undergone fertility treatment with IVF or are planning to get one or are just curious about the process, we got you. You are probably incredibly excited and full of questions about your pregnancy. One of the first things many people want to know is their due date. While due dates are always an estimate, IVF due dates can be calculated with a higher level of accuracy using an IVF Due Date Calculator. Read on to learn more about the IVF process, the IVF transfer due date, and the due date calculator. 

What is the IVF process?
Jump Tag Icon

In Vitro Fertilisation (IVF) is a modern way used to treat infertility. A woman's ovaries are stimulated with medication, and then the eggs are retrieved from the ovaries. The eggs are fertilised with sperm in a laboratory dish, and then the resulting embryos are transferred to the woman's uterus. The results depend on many factors, such as age, cause of infertility, and the embryos. IVF is a complex process that requires multiple steps and careful monitoring by a fertility specialist.

What Is an IVF Pregnancy Due Date and How Do We Calculate It?
Jump Tag Icon

The IVF Pregnancy Due Date Calculator estimates the due date of a pregnancy conceived through in vitro fertilisation. It is calculated through an IVF calculator. It calculates the date based on the egg retrieval date or the embryo transfer date and also takes into account the gestational age of the foetus.

Similarly, an In Vitro Fertilisation (IVF) Calculator is also used to estimate the chances of success for those undergoing IVF treatment. The tool considers factors such as age, number of previous successful pregnancies, number of eggs retrieved, and quality of those eggs. By putting this information into the calculator, the success rate of the pregnancy resulting from the IVF can be calculated.

How Do You Calculate Your Due Date If You Get Pregnant Without IVF?

In case you get pregnant without the IVF, you can calculate your due date using either of the three methods: 

IVF Transfer Due Date Calculator
Jump Tag Icon

The IVF Due Date Calculator provides an approximate due date, which is meant to be used only as a reference.  The actual due date may vary by a few days; therefore, it is important to consult your obstetrician before making big decisions regarding your pregnancy. It is important to work closely with your healthcare provider to monitor the health of the pregnancy and determine the most accurate due date. 

Your healthcare provider will also consider other factors, such as the baby's growth rate and any potential complications while determining the best course of action throughout the pregnancy.

Why you should know your due date
Jump Tag Icon

Knowing the due date is essential for medical professionals to track the pregnancy's progress—from the embryo transfer to the delivery date. This knowledge ensures the baby's growth is on track and identifies any potential issues that could arise. Mothers can also prepare for the arrival of their baby, plan maternity leave, and make childcare arrangements accordingly.

Factors that affect the due date in IVF pregnancies
Jump Tag Icon

Here are some factors that impact the due date when it comes to IVF pregnancies.

Age of the woman
Jump Tag Icon

IVF is in itself a complicated process, and women who are over the age of 35 may be at a higher risk for complications such as preterm labour or preeclampsia, which can affect the due date.

Number of embryos transferred
Jump Tag Icon

Transferring multiple embryos can increase the likelihood of a multiple pregnancy, which can affect the due date and increase the risk of complications. However, a higher number of embryos transferred can increase the transfer's success rate.
 

Quality of the embryos
Jump Tag Icon

Embryos that are of higher quality may be more likely to implant and develop into a healthy pregnancy, which can affect the due date.

Timing of the transfer
Jump Tag Icon

The timing of the embryo transfer can also affect the due date. If the transfer is done earlier or later than expected, it can impact the development of the foetus and the estimated due date. A 3-day embryo transfer is a Cleavage embryo, and a 5-day embryo transfer is a Blastocyst.

Other factors

Factors such as the woman's uterine lining thickness and overall health can also impact the timing of the transfer and therefore the due date.

Due Date Calculator IVF and Its Components
Jump Tag Icon

The due date is an estimated date of when a pregnant woman will deliver her baby. While often estimated as a single date, the Due Date can be helpful when considering a range of dates. It is interesting to note that only about 4% of the births take place on the actual due date. Below are the components of the IVF transfer Due Date Calculator :
 

Date of transfer
Jump Tag Icon

This refers to the embryo transfer date. Select the date on which you had your embryo transfer procedure done.

Day-3 Embryo Transfer
Jump Tag Icon

This refers to the days your embryo transfer took to be placed into the uterine environment. If you had a 3-day embryo transfer, please select Day  3 from the drop-down menu in the calculator above.

Day-5 Embryo Transfer
Jump Tag Icon

This also refers to the number of days it took for your embryo transfer to occur. If you had a 5-day embryo transfer, please select Day 5 from the drop-down menu in the calculator above.

There are other ways to calculate the IVF transfer due date. To calculate a fresh IVF, add 266 days to the date of transfer. If the transfer date extends to more than 5 days, you can simply subtract the number of days from 266 and then add the transfer date to it. 

Types of Transfers 
Jump Tag Icon

After collecting the egg from the mother and sperm from the father, an embryo is created in the lab. There are many ways to transfer this embryo into the mother’s womb depending on several factors, like the age of the mother and the type of transfer she opted for. 

There are mainly 2 types of transfers: Fresh and Frozen. Their features are highlighted in the table below:

Fresh Transfer

Frozen Transfer

Fresh transfers involve the immediate implantation of embryos created during an IVF cycle.

Frozen transfers involve freezing and storing embryos produced during an IVF cycle for delayed implantation at a later time. 

Fresh transfers offer better success rates in terms of conception. 

Frozen transfers fare less in terms of success rate when compared with Fresh transfers.

Fresh transfers need to be used immediately.

Frozen transfers can offer greater flexibility and convenience.

 

Talk to your physician to determine the best option for your unique situation. Regardless of the method used, remember that fresh and frozen transfers can be emotionally and physically taxing. Be sure to take care of yourself and your partner throughout the process.

Genetic testing and embryo transfer
Jump Tag Icon

If you have undergone genetic testing, it can help your doctor select the healthiest embryos for transfer, potentially increasing the procedure's success rate. The most appropriate time for embryo transfer typically depends on the stage of development of the embryos. Day 5 or 6 is often the best time for transfer, as the embryos are usually in the blastocyst stage. However, genetic testing can also delay the timing of the transfer. Your doctor will discuss the potential benefits and drawbacks of genetic testing with you and help you make an informed decision.

Conclusion
Jump Tag Icon

The IVF Due Date Calculator provides an accurate method to estimate delivery dates for pregnancies conceived through in vitro fertilisation. By considering factors like the embryo transfer date and gestational age, it offers a reliable timeline for expectant parents to prepare for childbirth and for healthcare providers to monitor pregnancy progress effectively. This tool is especially beneficial in IVF pregnancies, where precise timing plays an important part in tracking the foetus's development and ensuring both maternal and child health.
