Hypothesis

Can emergency contraception lead to heterotopic pregnancies?

Conclusion

This case highlights the importance of considering heterotopic pregnancy in patients with abdominal pain or vaginal bleeding, even after detecting an intrauterine pregnancy.

Supporting Evidence

  • Heterotopic pregnancy is rare but can occur after emergency contraception.
  • Prompt diagnosis and management are crucial to prevent complications.
  • Emergency contraception may not prevent ectopic pregnancies if ovulation has already occurred.

Takeaway

Sometimes, a woman can have a pregnancy in her uterus and another in her fallopian tube at the same time, which is very rare. This can happen even after taking emergency contraception.

Methodology

The case was managed through surgical intervention after thorough diagnostic work-up including ultrasonography.

Limitations

The study is based on a single case report, limiting generalizability.

Participant Demographics

A 29-year-old primigravid woman.
