Enter your details above and the result will appear here.
How to use
- Choose retrieval, day 3 transfer or day 5 transfer.
- Enter the date it happened (or is planned).
- Your estimated due date appears instantly.
Tips
- Pick the exact event type - a day 5 transfer gives a different due date than a day 3 transfer.
- This is an estimate for planning; your clinic's ultrasound dating is the medical reference.
- If the transfer date is planned (not yet done), treat the result as provisional.
- Always confirm key dates with your fertility doctor before making arrangements.
Note
Due dates count 266 days from conception (retrieval). A day 3 transfer is already 3 days along, so 263 days remain; a day 5 blastocyst transfer has 261 days remaining. Your clinic dates the pregnancy from scans as well, and most babies do not arrive on the exact date. Estimate only — not medical advice.
