Obstetric Ultrasonography - Early Pregnancy

Early Pregnancy

The gestational sac can sometimes be visualized as early as four and a half weeks of gestation (approximately two and a half weeks after ovulation) and the yolk sac at about five weeks gestation. The embryo can be observed and measured by about five and a half weeks. The heartbeat may be seen as early as 6 weeks, and is usually visible by 7 weeks gestation. Coincidentally, most miscarriages also happen by 7 weeks gestation. The rate of miscarriage, especially threatened miscarriage, drops significantly if normal heartbeat is detected.

Famous quotes containing the words early and/or pregnancy:

    The setting sun is reflected from the windows of the alms-house as brightly as from the rich man’s abode; the snow melts before its door as early in the spring. I do not see but a quiet mind may live as contentedly there, and have as cheering thoughts, as in a palace.
    Henry David Thoreau (1817–1862)

    If pregnancy were a book they would cut the last two chapters.
    Nora Ephron (20th century)
