Warning Signs - Seek Immediate Care
Recommendations
Attend all scheduled prenatal appointments.
Monitor fetal movement daily after 28 weeks (kick counts).
Report any decrease in fetal movement immediately.
Sleep on your side (left preferred) after 28 weeks.
Maintain a healthy diet and stay hydrated.
Avoid smoking, alcohol, and recreational drugs.
Protective Actions
Sleep Position
Sleep on your side after 28 weeks. Studies show reduced risk with side sleeping.
Kick Counts
Track fetal movements daily after 28 weeks. Report changes to your provider.
Prenatal Care
Attend all scheduled appointments. Early detection of problems saves lives.
Lifestyle
Avoid smoking, alcohol, and drugs. Maintain healthy diet and moderate activity.
Fetal Movement Monitoring
Changes in fetal movement are one of the most important warning signs. Here's how to monitor:

Risk by Gestational Age
| Weeks | Risk Level | Baseline Risk | Notes |
| 20-28 | Lower | 1.5-2/1000 | Early viability period |
| 28-36 | Moderate | 2-3/1000 | Most monitoring begins |
| 37-39 | Moderate | 2-3/1000 | Early term period |
| 40+ | Increasing | 3-5/1000 | Post-term risk rises; delivery often recommended |
🚨 Seek Immediate Care If:
- •Baby's movements significantly decrease or stop
- •Severe abdominal pain or cramping
- •Vaginal bleeding (any amount)
- •Severe headache, vision changes, or swelling
- •Fluid leaking from vagina
- •Fever or signs of infection
- •Any feeling that something is wrong
Trust your instincts. Always call your provider if concerned.

Understanding Stillbirth Risk Assessment
Stillbirth is defined as the loss of a baby at or after 20 weeks of pregnancy. In developed countries, the rate is approximately 3-5 per 1,000 births. While many stillbirths cannot be prevented, research shows that identifying and addressing modifiable risk factors can significantly reduce risk - up to 30% of stillbirths may be preventable.
Important: This calculator provides general risk information based on population studies. It cannot predict individual outcomes. Always discuss your specific situation with your healthcare provider.
Evidence-Based Assessment
Uses data from large population studies including the Stillbirth Collaborative Research Network.
Data Sources:
- SCRN Studies
- Lancet Stillbirth Series
- RCOG Guidelines
Modifiable Risk Focus
Highlights factors you can address to reduce your personal risk level.
Key Interventions:
- Smoking cessation
- Sleep position
- Kick counting
Personalized Guidance
Generates specific recommendations based on your individual risk profile.
Includes:
- Prevention strategies
- Warning signs
- Monitoring guidance
How Does Risk Assessment Work?
This calculator evaluates multiple risk factors identified in stillbirth research and calculates a relative risk compared to the general population. Each factor contributes additively or multiplicatively to your overall risk profile.
🔬 Assessment Methodology
Risk Calculation
- 1Evaluate demographic risk factors (age, BMI, ethnicity)
- 2Assess obstetric history (prior stillbirth, parity)
- 3Identify modifiable factors (smoking, sleep position)
- 4Calculate combined relative risk score
Key Evidence
- Smoking cessation reduces risk by ~50%
- Side sleeping reduces risk by ~50%
- Kick counting enables early intervention
- Regular prenatal care improves outcomes
When to Use This Calculator
Early Pregnancy
Identify modifiable risks early for maximum prevention opportunity.
Care Planning
Discuss risk factors and monitoring plans with your provider.
Third Trimester
Understand the importance of kick counting and when to seek care.
Risk Factors Explained
Non-Modifiable Factors
- • Advanced maternal age (35+): 1.5-2x higher risk
- • Prior stillbirth history: 2-10x higher risk
- • African American ethnicity: 2x higher risk
- • Multiple pregnancy: 5x higher risk
- • Certain genetic conditions
Modifiable Factors (You Can Change)
- • Smoking: Quitting reduces risk ~50%
- • Sleep position: Side sleeping reduces risk ~50%
- • Obesity: Weight management helps
- • Diabetes: Good glucose control
- • Blood pressure: Treatment reduces risk
- • Prenatal care: Regular attendance
Kick Counting - Monitoring Fetal Movement
Starting at 28 weeks, monitoring your baby's movement patterns is one of the most important things you can do. Every baby has their own pattern - learn what's normal for yours.
⚠️ When to Seek Care Immediately
- • Fewer than 10 movements in 2 hours (when baby usually active)
- • Significant change from baby's normal pattern
- • Baby not moving at usual times
- • "Something doesn't feel right" - trust your instincts
Frequently Asked Questions
Can stillbirth be prevented?
While not all stillbirths can be prevented, research suggests up to 30% could be prevented by addressing modifiable risk factors. Key interventions include smoking cessation, side sleeping after 28 weeks, kick counting, and regular prenatal care.
Why does sleep position matter?
After 28 weeks, sleeping on your back can compress major blood vessels (inferior vena cava and aorta) and reduce blood flow to the baby. Studies show side sleeping (left side preferred) reduces stillbirth risk by approximately 50%.
How do I count kicks correctly?
Count kicks when your baby is usually most active (often evenings). Lie on your side and count any distinct movements. You should feel at least 10 movements within 2 hours. Know your baby's pattern - any significant change warrants contacting your provider.
What if I'm higher risk?
Higher risk pregnancies may require additional monitoring such as more frequent prenatal visits, growth ultrasounds, non-stress tests, and earlier delivery planning. Your provider will create a personalized care plan based on your specific factors.
