How This Calculator Works
Aggregates medical data from Dugas (2019) and maternal age parameters to map general population risk probability.

Analyzing Weekly Risk Reductions
While early miscarriage occurs in roughly 10-20% of recognized pregnancies, the percentage falls below 5% by week 8 and under 1% once you hit the second trimester.
Age as a Modifying Metric
Maternal age influences risk profiles due to changes in egg chromosomal quality over time.
Clinical Standard Reference Guideline:
