Latest OB appt.

Today we went in for our 3rd OB appointment. We didn't get to see the baby this time, but we were able to hear the heartbeat. She told us they still are not sure if the ultrasound machines have any negative effect on the baby so they don't want to do one every time we go in.

To finally answer the question: "what's the difference between the machine they use in the office, and going to radiology?" Our Dr. told us the machines are the same, but in radiology, there are trained professionals who measure the baby and check for certain things. In her office, we just look at the baby and get a picture, but she doesn't do anything else.

In 3 weeks we go the radiologist for an official ultrasound, and we may be able to find out the gender of the baby.

Your pregnancy: 15 weeks

How your baby's growing:

Your growing baby now measures about 4 inches long, crown to rump, and weighs in at about 2 1/2 ounces (about the size of an apple). She's busy moving amniotic fluid through her nose and upper respiratory tract, which helps the primitive air sacs in her lungs begin to develop. Her legs are growing longer than her arms now, and she can move all of her joints and limbs. Although her eyelids are still fused shut, she can sense light. If you shine a flashlight at your tummy, for instance, she's likely to move away from the beam. There's not much for your baby to taste at this point, but she is forming taste buds. Finally, if you have an ultrasound this week, you may be able to find out whether your baby's a boy or a girl! (Don't be too disappointed if it remains a mystery, though. Nailing down your baby's sex depends on the clarity of the picture and on your baby's position. He or she may be modestly curled up or turned in such a way as to "hide the goods.")
