What Week Is the Placenta Seen?

Published in Pregnancy and Fetal Development 2 mins read

The placenta is a vital organ that develops during pregnancy to nourish and support the growing baby. It usually becomes visible on an ultrasound around week 6 of pregnancy.

Here's a breakdown of how the placenta develops and when it can be seen:

  • Weeks 3-4: The fertilized egg implants in the uterine lining, and the placenta starts to form.
  • Week 5: The placenta is still very small and not yet visible on ultrasound.
  • Week 6: The placenta is developing rapidly and should be visible on a transvaginal ultrasound.
  • Week 7-10: The placenta grows larger and becomes more visible on a transabdominal ultrasound.

Factors that can affect when the placenta is seen on ultrasound:

  • Ultrasound type: Transvaginal ultrasounds are more sensitive than transabdominal ultrasounds and can often detect the placenta earlier.
  • Individual variations: The size and development of the placenta can vary slightly from person to person.
  • Gestational age: In some cases, the placenta may be visible slightly earlier or later than expected.

If you have any concerns about the development of your placenta, please consult your healthcare provider.
