Due date by IVF transfer
Shell landing for people who typed “due date by IVF.” Same transfer + day-age engine as the main IVF due date calculator. Estimate only — not medical advice.
Enter a transfer date to see an estimate.
What this page does
IVF dating uses transfer date and embryo age, not a fictional period. Day 5 → +261, Day 3 → +263, Day 6 → +260 under the common 266 − age framework.
This page exists so the “by IVF” query has a clear door into the same math without inventing a second formula.
When to use
You searched “due date by IVF” and have a transfer date + day age.
When not to
Override ultrasound dating. Missing transfer date.
Assumptions
Browser-only planning arithmetic. Defaults are disclosed on the page. Ultrasound and clinic policy override this tool.
Examples
Day 5 transfer Mar 10, 2026 → EDD Nov 26, 2026.
Day 3 transfer Jun 1, 2026 → EDD Feb 19, 2027.
Gotchas
Clinic dating after ultrasound can differ from browser math — the clinic wins for medical decisions.
Wrong input dates (retrieval vs transfer, spotting vs true LMP) slide every result.
Estimate only — not medical advice.
How this is calculated
The math stays in your browser. Enter the dates you actually know, read the estimate, and treat clinic ultrasound dating as the authority when it disagrees.
Nothing here is medical advice, a diagnosis, or a substitute for prenatal care.
