1. No Medical Advice
The content provided on **IVF Due Date Calculator** (ivfduedatecalculator.site), including text, graphics, images, calculators, and other materials, is for **informational and educational purposes only**. This website does not provide medical advice, diagnosis, or treatment. The information presented here is not intended to be a substitute for professional medical advice, diagnosis, or treatment.

**Never disregard professional medical advice or delay in seeking it because of something you have read on this website.**
2. Accuracy of Calculations
Our IVF Due Date Calculator uses standard medical formulas based on the date of embryo transfer (Day 3 or Day 5) to estimate your due date.
- **Day 3 Embryos:** Calculated as Transfer Date + 263 Days.
- **Day 5 Embryos:** Calculated as Transfer Date + 261 Days.
While we strive for accuracy based on these standard algorithms, **every pregnancy is unique**. Your actual due date may differ based on:
- Ultrasound measurements (Crown-Rump Length).
- Individual fetal development rates.
- Clinical decisions made by your healthcare provider.
**The result provided by this calculator is an estimate only.** It should not be used to schedule medical procedures or make critical health decisions without confirmation from your doctor.
3. Ultrasound vs. Calculator Dates
In IVF pregnancies, the "Transfer Date" is a biological fact. However, it is common for doctors to adjust due dates based on early ultrasound measurements if there is a significant discrepancy (usually >5-7 days). In such cases, **always defer to the due date provided by your doctor** based on the ultrasound findings.
