Transvaginal and transabdominal ultrasounds allow women to see a developing baby or babies in their womb. During the first three weeks after conception, ultrasound technicians can't usually take any measurable images with an ultrasound. Around week four, you can see the gestational sac -- a cocoon-like structure that helps form the placenta. Ultrasounds can detect the earliest images of your baby around five weeks after conception. The fetus is about the size of an ink-pen dot, but technicians can magnify the image using computer software.

Ultrasound Accuracy: Is It a Boy or a Girl?
Ultrasounds have a variety of purposes during pregnancy, but the use that often receives the most attention is its ability to reveal the sex of the baby. Some parents-to-be can't wait to find out whether they're having a boy or a girl, while others choose to put off knowing the sex until birth. Either way, a sonogram — the grainy, black-and-white image that results from an ultrasound scan — will be baby's earliest picture and a couple's first chance to see the developing fetus.
Most parents today will want to find out the sex of their baby before the birth. One of the most common ways to do this is with an ultrasound , most frequently performed at between 18 and 20 weeks of gestation. According to a study published in the journal Obstetrics and Gynecology , no less than 69 percent of parents wanted to know.
