First — I am very sorry for your loss. A 19-week loss after everything looked normal is emotionally devastating. Your questions are valid. I will answer clearly and honestly.
⸻
From what you described:
• All genetic screenings normal
• Baby growth appropriate (361 g at 19 weeks is normal)
• Heartbeat normal
• Sudden loss around 19 weeks
• Diagnosis: Cervical incompetence (cervical insufficiency)
• Wife BMI: 36
This pattern strongly fits cervical insufficiency, not genetic abnormality, not semen issue, and not something you “missed.”
Why does cervical insufficiency happen?
It is usually due to:
• Structural weakness of cervix
• Prior cervical procedures (if any)
• Congenital collagen weakness
• Sometimes no identifiable cause
It is mechanical failure, not fetal problem.
Was BMI 36 the cause?
Obesity increases pregnancy risks (
diabetes, hypertension), but it is not a primary cause of cervical incompetence.
So please understand clearly:
➡️ This was NOT your fault
➡️ Not because of semen
➡️ Not because baby was unhealthy
➡️ Not because tests were wrong
It is usually a structural cervical issue.
Next Steps
For next pregnancy:
✔ Cervical Cerclage (stitch)
Yes — cerclage significantly improves outcomes in proven cervical incompetence.
Types:
• History-indicated cerclage (placed at 12–14 weeks)
• Ultrasound-indicated (if cervix shortens)
Success rates:
• 80–90% carry pregnancy beyond viability when properly timed.
✔ Pre-pregnancy planning
• Weight reduction before next conception (target BMI
Health Tips
✔ Do not blame yourself
✔ Allow emotional recovery before next attempt
✔ Target weight reduction gradually (not crash dieting)
✔ Next pregnancy should be managed as high-risk from day one
✔ Choose a center experienced in cerclage
Many couples with cervical incompetence go on to have completely healthy babies with timely stitching.
This loss does not mean you cannot have a child — it means next pregnancy needs structured planning.
