Understanding IVF Due Date Calculations
Why IVF Dating is Different
IVF due date calculations are more precise than natural conception because we know the exact fertilization date. The calculation depends on the embryo development stage at transfer, making it more accurate than traditional LMP-based calculations.
Key Differences:
- • Known Fertilization: Exact timing eliminates guesswork
- • Embryo Stage: Development stage affects calculation
- • No LMP Needed: Transfer date is the reference point
- • Higher Accuracy: More precise than natural conception dating
Multiple Pregnancy Considerations
Multiple pregnancies from IVF (twins, triplets) often have different timelines than singleton pregnancies. They typically deliver 2-4 weeks earlier and require closer monitoring throughout pregnancy.
Multiple Pregnancy Facts:
- • Earlier Delivery: Average 2-4 weeks before due date
- • Increased Monitoring: More frequent check-ups required
- • Higher Risk: Complications more common
- • Specialized Care: Maternal-fetal medicine referral often needed
