IUDs are 99% effective, but pregnancy can still occur
Pregnancies with an IUD carry potential medical risks
Immediate medical consultation is crucial if pregnancy is suspected
Not all IUD pregnancies result in complications
Birth control is a deeply personal choice, and while methods like intrauterine devices (IUDs) are highly effective, rare exceptions do happen. The viral story of baby Dexter, nicknamed the "Mirena baby," highlights an extraordinary medical occurrence that sparks important conversations about birth control methods.
Modern contraceptive technologies have dramatically improved, offering women unprecedented control over reproductive choices. However, no method is absolutely foolproof. When an unexpected pregnancy occurs with an IUD in place, understanding potential risks and next steps becomes critical for maternal and fetal health.
IUDs like Mirena are designed with impressive birth control precision. Manufacturers claim 99% effectiveness, which means fewer than one in 100 women will become pregnant annually while using this method. Despite these statistics, rare cases like Lucy Hellein's demonstrate that medical anomalies can and do occur.
When pregnancy happens with an IUD, several significant medical concerns emerge. Ectopic pregnancies represent one of the most serious potential complications. These occur when a fertilized egg implants outside the uterus, typically in the fallopian tubes, which can pose severe health risks to the mother.
Other potential risks include:
Increased chance of miscarriage
Higher risk of premature delivery
Potential severe infections
Complicated fetal development
If you suspect pregnancy while using an IUD, immediate medical consultation is essential. Healthcare providers will typically:
Conduct blood tests to confirm pregnancy
Monitor hCG hormone levels
Assess potential complications
Determine safe IUD removal procedures
