FET Calculator
If you’re undergoing an IVF treatment or have had an embryo transfer, tracking your pregnancy journey is essential. With our FET Calculator, you can quickly and accurately calculate important pregnancy milestones, including your due date, conception date, and gestational age. Whether you want to know your current trimester, or calculate key pregnancy milestones, this tool simplifies the process.
Introduction to the FET Calculator
The FET Calculator is designed to assist those who have undergone a Frozen Embryo Transfer (FET). This tool allows users to track pregnancy progress with accurate data, helping them determine key dates like due date, gestational age, and milestones. It considers factors like the embryo transfer date and embryo age (Day 3, Day 5, or Day 6) to provide precise calculations.
By inputting a few key details such as your embryo transfer date and embryo age, you’ll instantly get an overview of your pregnancy journey. Whether you’re preparing for your baby’s arrival or just keeping track of your milestones, this calculator is the perfect tool.
How to Use the FET Calculator
The FET Calculator is easy to use and provides results instantly. Here’s how you can use the tool:
1. Select the Embryo Transfer Date
Begin by selecting the embryo transfer date. This date is crucial as it marks the beginning of your pregnancy timeline.
2. Select the Embryo Age
The next step is to choose the embryo age at the time of transfer. The available options are:
- Day 3 Embryo
- Day 5 Embryo (Blastocyst) (default selection)
- Day 6 Embryo (Blastocyst)
The age of the embryo affects the pregnancy calculation, as the development of the embryo can impact the pregnancy timeline.
3. Choose What to Calculate
You can choose from three types of calculations:
- Due Date: Calculate your due date based on your embryo transfer date and embryo age.
- Current Gestational Age: Find out how many weeks and days pregnant you are.
- Pregnancy Milestones: Track important pregnancy milestones like the end of the first trimester, viability scan, anatomy scan, and more.
4. Calculate
Click the Calculate button, and the tool will instantly display your results. If you wish to reset the data, click the Reset button to clear the form.
FET Calculator Results: What You’ll See
Once you’ve input the required information and clicked “Calculate,” the FET Calculator provides a comprehensive result:
1. Due Date
The due date will be displayed based on the average 280-day gestation period, which starts from your Last Menstrual Period (LMP).
2. Conception Date
The conception date is calculated based on the embryo transfer date and embryo age. This is important as it indicates when fertilization likely occurred.
3. Gestational Age Today
This tells you how many weeks and days pregnant you are, based on the LMP date.
4. Trimester
The trimester you’re in will be calculated based on your gestational age. The tool identifies if you’re in the First Trimester, Second Trimester, or Third Trimester.
5. Days/Weeks Until Due Date
The calculator will show you how many days and weeks are left until your due date, helping you prepare for your baby’s arrival.
Pregnancy Milestones
If you select the Pregnancy Milestones option, you’ll get a table outlining important events during your pregnancy. These milestones include:
- End of First Trimester (Week 13)
- Start of Second Trimester (Week 14)
- Anatomy Scan (Week 20)
- Viability (Week 24)
- Start of Third Trimester (Week 28)
- Full Term (Week 37)
- Due Date (Week 40)
These milestones provide a roadmap for your pregnancy, helping you keep track of key moments.
Example of Using the FET Calculator
Let’s take a quick example of how the FET Calculator works.
Scenario:
- Embryo Transfer Date: May 1, 2026
- Embryo Age: Day 5 Embryo (Blastocyst)
- Calculation Type: Due Date
Based on this input, the calculator will:
- Calculate the due date, which is approximately 280 days from the Last Menstrual Period (LMP).
- Provide the conception date, approximately five days before the embryo transfer.
- Determine the gestational age (e.g., “4 weeks, 2 days”).
- Show the trimester (e.g., “First Trimester”).
- Indicate how many days and weeks are remaining until the due date.
If you choose the Pregnancy Milestones option, it will list the significant events in the pregnancy with corresponding dates.
