At seven weeks of gestation it is still too early to identify what gender sex the baby will be. It is also impossible to do a thorough foetal screening assessment because it is still just too premature in terms of embryonic development. In some respects the seven week ultrasound can be quite accurate because the embryo is developing very quickly.

They are also not as mobile and active as they will be with future development. So obtaining accurate measurements and visualising them clearly on the screen is a little easier than when they are able to do somersaults and move around a lot.

Yes, you should be able to. This is also more likely if you are having a transvaginal ultrasound. But by the time the baby has developed to full term, this rate increases to around BPM. One of the reasons for this is because the heart needs to work harder and more efficiently to pump oxygenated blood around its much larger body and brain. The quality of the equipment and the skill of the sonographer are very important when doing any pregnancy ultrasound. Like every other health professional, individual skill, expertise and training make a big difference to the outcome of their assessments.

When you are first referred for a seven week ultrasound, the first of many types of ultrasound , ask your GP or maternity care provider who has the best reputation for quality scan results. You may also like to ask your friends who have had a positive experience and to see who they would recommend in terms of having firsthand experience.

7 Week Ultrasound

Tell us a little bit about your child. Gender Don't know yet Boy Girl. You take a home pregnancy test and a plus sign appears. Time to get "official" confirmation at the ob-gyn's office with a blood test and an ultrasound exam. What to expect at your exam Your first ultrasound, also known as a sonogram, will take place when you're around 6 to 8 weeks pregnant. When you schedule your appointment, be sure to ask whether you need a full bladder for the test. Sound waves travel better through liquid, so a full bladder can enhance the quality of your ultrasound.

As your uterus and the fetus grow and you have more amniotic fluid , a full bladder matters less. At this stage, your baby is very small and your uterus and fallopian tubes are closer to your birth canal than to your abdomen, so your ob-gyn will conduct the test transvaginally to get a clearer picture. The test is painless. Your ob-gyn will place a thin, wand-like transducer probe, which transmits high-frequency sound waves through your uterus, in your vagina.

The sound waves bounce off the fetus and send signals back to a machine that converts these reflections into a black and white image of your baby. It will be hard to see much in this first snapshot, but a clearer photo will come around 13 weeks, which is the ideal time to share your exciting news.

Why it's important Your ob-gyn listens for your baby's heartbeat and estimates his age by measuring his length from head to bottom; the baby is tiny in the first trimester and is growing about a millimeter a day. From this test, your doctor will be able to determine a more accurate due date and track milestones during your pregnancy. Your ob-gyn will also rule out a tubal ectopic pregnancy, which is when the fetus grows in the fallopian tube instead of the uterus. This occurs only 1 percent of the time.

And your doctor will also be able to tell if you're pregnant with multiples. Other tests All pregnant women are offered a nuchal translucency NT test, performed between 11 and 13 weeks, and this involves another ultrasound. The NT evaluates your risk of having a baby with Down syndrome, trisomy 18 another chromosomal abnormality , or certain heart defects.

What to expect at your exam This ultrasound, called an anatomy scan, lasts 20 to 45 minutes if you're having one baby, longer if you're having multiples. Your ob-gyn uses it to assess the baby's growth and make sure all of her organs are developing properly.

The doctor will check your baby's heart rate and look for abnormalities in her brain, heart, kidneys, and liver. She'll count your baby's fingers and toes, check for birth defects, examine the placenta, and measure the amniotic fluid level.

And she'll probably be able to determine your sweet pea's sex, although it's not a slam dunk; an experienced tech gets it right more than 95 percent of the time. If you don't want to know your baby's sex, let her know ahead of time. You might even get a 3-D view, which will offer a true-to-life glimpse of your baby's nose and bone structure.

Don't worry—when she arrives she'll be cuter than the alien-like image she presents on the TV screen!
