If you're like most women, you'll have a routine ultrasound so your doctor can get information on your baby's health. Though this brief (5 to 10 minutes) and painless test is most often done during the second trimester, it can be performed any time between the fifth week of gestation and delivery.
Get a glimpse inside your swelling belly and see how babies grow and change with this ultrasound identifier visual tool. These dynamic images will show you what a fetus looks like at 17, 19, and 30 weeks.
