1. What is Miscarriage Risk Calculation?

Miscarriage risk calculation estimates the probability of pregnancy loss based on gestational age and individual risk factors. The risk decreases significantly as pregnancy progresses, with the highest risk occurring in the first trimester.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Base Risk \) — Baseline miscarriage risk percentage for the gestational week
• \( Adjustment \) — Factor accounting for individual risk factors (medical history, age, etc.)

Explanation: The base risk varies by gestational week, while the adjustment factor modifies this based on individual circumstances.

3. Importance of Miscarriage Risk Assessment

Details: Understanding miscarriage risk helps in pregnancy management, provides reassurance as pregnancy progresses, and guides medical decisions for high-risk pregnancies.

4. Using the Calculator

Tips: Enter the current gestational week (4-20), baseline risk percentage for that week, and an adjustment factor based on individual risk factors. All values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: How does miscarriage risk change by week?
A: Risk decreases significantly after the first trimester, with the highest risk occurring between weeks 4-8.

Q2: What factors affect the adjustment value?
A: Maternal age, previous miscarriage history, medical conditions, lifestyle factors, and genetic factors can all influence the adjustment value.

Q3: When is miscarriage risk highest?
A: The highest risk occurs in the first trimester, particularly between weeks 4-8 of pregnancy.

Q4: Are there limitations to this calculation?
A: This provides an estimate only. Individual circumstances vary, and professional medical advice should always be sought.

Q5: What is considered a normal miscarriage risk?
A: Risk varies significantly by gestational age. By week 20, the risk typically drops below 1-2% for most pregnancies.
