Yes, a 5-week ultrasound can sometimes miss twins. At this early stage, it can be challenging to identify multiple embryos due to their small size and the limitations of ultrasound technology. Factors such as the position of the embryos and the technician's experience can also affect visibility. Subsequent ultrasounds, often conducted between 8-12 weeks, are more reliable for confirming the presence of twins as the embryos grow and become more distinguishable.

FAQs & Answers

  1. What are the signs of a twin pregnancy in early ultrasound? Early signs of a twin pregnancy may include higher hormone levels, and an ultrasound may show more than one gestational sac.
  2. When is the best time to detect twins via ultrasound? The best time to confirm twins through ultrasound is typically between 8 to 12 weeks as the embryos are larger and more identifiable.
  3. Can ultrasounds detect pregnancies earlier than 5 weeks? Yes, some ultrasounds can detect pregnancies as early as 4 to 5 weeks, but clarity improves in later weeks.
