Fertility & Clinical Health Disclaimer: IVF due dates are among the most mathematically precise in obstetrics because the exact time of fertilization or transfer is known. However, only ~5% of babies arrive on their exact calculated due date. Always consult your reproductive endocrinologist or OB-GYN for formal medical monitoring.
What is IVF & Conception Due Date Calculator?
The IVF Due Date Calculator determines the exact estimated date of delivery (EDD), gestational age, and fetal developmental timeline for pregnancies conceived through in vitro fertilization (IVF), frozen embryo transfers (FET), egg retrieval, or intrauterine insemination (IUI). All obstetric ART calculations run privately in your browser.
Designed for accuracy, speed, and privacy, this tool runs entirely on your local device with zero network latency.
How to Use the IVF & Conception Due Date Calculator
- 1Select your Assisted Reproductive Technology (ART) procedure type: "Day 5/6 Blastocyst Transfer", "Day 3 Embryo Transfer", "Egg Retrieval / Ovulation Date", or "IUI / Conception".
- 2Select the exact date your transfer, retrieval, or insemination procedure occurred.
- 3Review your official obstetric estimated delivery date (EDD), current gestational weeks and days, and trimester schedule.
Formula & Calculation Logic
Calculates obstetric gestational age based on exact embryological development at transfer: since human gestation averages 266 days post-fertilization, transferring a Day 5 blastocyst leaves exactly 261 days until delivery.
EDD(Day 5 Transfer) = Transfer_Date + 261 Days | EDD(Day 3 Transfer) = Transfer_Date + 263 Days | EDD(Retrieval) = Retrieval_Date + 266 DaysIVF & Conception Due Date Calculator Frequently Asked Questions
