Disclaimer
Updated September 2026 · Educational estimates only
IVF Due Date Calculators is an educational website. It is not a fertility clinic, laboratory, pharmacy, hospital, or medical practice. The editor is Dr. Farhan. Using the calculator, reading a guide, or sending an email does not make Dr. Farhan your treating physician through this website and does not create a doctor–patient relationship.
The Android listing on Google Play is the same educational math in an app wrapper. It is also not a medical device that diagnoses pregnancy, ectopic risk, or miscarriage.
What the numbers are
The tool applies published ART counting: clinic date plus 266 days minus embryo age. Day 5 blastocyst = +261 from transfer. Day 3 = +263. Day 6 = +260. Day 7 = +259. Retrieval or IUI usually = +266. Frozen storage time is not added. About 4–5% of babies arrive on the exact calendar day. We check that framing against public documents such as ACOG Committee Opinion 700 and CDC ART resources. We do not invent a private “clinic formula.” A page on this site is not a signed consult for your chart.
A first-trimester ultrasound that agrees within about five days often keeps the IVF date. Later scans are poorer dating tools. If your team uses a different convention (for example dating from trigger shot or from a measured crown–rump length), their chart wins. Copy our card into a note if it helps the conversation; do not overwrite a hospital portal from this website.
What this site cannot do
- Diagnose ectopic pregnancy, miscarriage, OHSS, chemical pregnancy, or implantation
- Interpret your personal beta trend, progesterone level, or ultrasound PDF
- Tell you to change medication, cancel a transfer, or pick a protocol
- Guarantee live birth, a specific due date, or that a hospital portal will match our card
- Replace the embryology report that states embryo day
Ads and affiliates
If Google AdSense or another network is live, those ads are not clinical recommendations. We do not let advertisers edit Day 3 / Day 5 offsets. A supplement, clinic, or test ad is not an endorsement. See Privacy and Cookies.
External links
Links to ACOG, CDC, ASRM, ESHRE, Google Play, and similar sources are for reference. We do not control their content or availability. If a link 404s, email the URL and we will fix our side.
Emergencies
Heavy bleeding (soaking pads), severe one-sided pain, fainting, chest pain, painful calf swelling, or rapidly worsening bloating after egg retrieval: call your clinic or emergency services the same day. Do not wait for an email reply from this website.
Limitation
To the extent allowed by law, IVF Due Date Calculators and the editor are not liable for decisions made from an educational estimate, including travel, leave from work, or medication timing. Your clinic chart remains authoritative. Full terms: Terms of use.
