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:
“To be candid, in Middlemarch phraseology, meant, to use an early opportunity of letting your friends know that you did not take a cheerful view of their capacity, their conduct, or their position; and a robust candour never waited to be asked for its opinion.”
—George Eliot [Mary Ann (or Marian)
“Back in the days when men were hunters and chestbeaters and women spent their whole lives worrying about pregnancy or dying in childbirth, they often had to be taken against their will. Men complained that women were cold, unresponsive, frigid.... They wanted their women wanton. They wanted their women wild. Now women were finally learning to be wanton and wild—and what happened? The men wilted.”
—Erica Jong (b. 1942)
