⚠️ Important Medical Disclaimer

This calculator provides estimates based on embryo transfer dates and is more accurate than LMP-based calculations for donor egg IVF pregnancies. However, individual pregnancies may vary, and actual due dates can differ by up to 2 weeks from estimates. Multiple pregnancies (twins, triplets) may deliver earlier than singleton due dates. Always follow your healthcare provider's monitoring schedule and due date assessments. Dating ultrasounds performed between 6-10 weeks are considered the gold standard for confirming gestational age and adjusting due dates if necessary.
