Product Overview
DueDateKit provides a pregnancy due date calculator with an IVF-focused option for parents who conceived through fresh embryo transfers or frozen embryo transfer (FET). It estimates the due date from the exact embryo transfer date and the embryo type (Day 3, Day 5, or Day 6), returning an estimated due date along with the current pregnancy stage.
The IVF calculator is designed to follow medically recognized embryo transfer calculation guidance and is built to run in the user’s browser. DueDateKit is available without registration, works across devices, and supports multiple languages for broader accessibility.

How DueDateKit - Your Pregnancy Due Date Calculator works
- 1
Choose embryo transfer day
Select the embryo type (Day 3, Day 5, or Day 6) that matches the IVF protocol.
- 2
Enter the transfer date
Input the exact date the embryo was transferred.
- 3
Review due date and stage

Use cases
- A parent using an IVF clinic’s transfer schedule can enter the embryo type and exact transfer date to estimate the due date and see the current pregnancy stage immediately.
- After a frozen embryo transfer (FET), a user can switch to the FET due date workflow, input the transfer date, and receive an estimated due date based on the embryo’s day-of-development.
- A couple with a known transfer plan (fresh cycle or FET) can calculate multiple timeline checkpoints (e.g., different embryo day types) to understand how the due date estimate changes with embryo age.
Who is it for?
DueDateKit is for expecting parents and patients navigating IVF, including fresh transfers and frozen embryo transfer (FET). It’s especially useful for those who need due date estimates based on embryo transfer day and exact transfer dates.
