Sonogram (Definition)

The sonogram is a test that looks at body organs with no radiation. It uses sound waves and can give us a 2 dimensional view of organs such as the kidney, liver, heart, and lungs. It can define spaces that are either solid or full of fluid. I can also guide large needles into an organ or near the spine, and can help define the area being cut open. Its a ...Read more

Had ultrasound at 6. 2 weeks one had heartbeat 122. Dr said was a twin other sac in ultrasound will I expel it empty sac or does it go away?

Dissolves: Commonly twin gestation turns into single one due to loss of one fetus. As long as this happens early, there is usually no consequences for the remaining fetus. The other one is reabsorbed. Usually this happens for a good reason, and may mean one is not healthy. You could not have prevented it or caused it either. Get followup U/S to make sure you baby is growing well inside you. Best wishes !! ...Read more

Hey i'm 6 weeks and 6 days pregnant and just had ultrasound showing bub with heartbeat at 170bpm. Is this normal or should I worry?

Hey i'm 6 weeks and 6 days pregnant and just had ultrasound showing bub with heartbeat at 170bpm. Is this normal or should I worry?

Don't Worry: Worrying won't help anything. Fetal heart rate usually peaks at 9-10 wks at 170 BPM so 170 at 7 weeks is a little high. Much too early to think about doing anything and an isolated reading should not be given too much weight. Followup studies will probably be ok. Heart can be better evaluated after 12 weeks. ...Read more

First ultrasound last 09/22/2014 there were two embryos . One 6 weeks and 5 days, other 6 weeks and 3 days. However, no heartbeat was found. ?

Need follow up: You will need a follow up ultrasound in 1 -2 weeks to evaluate the status of the findings. Sometimes the embryo is too small to clearly show a heartbeat prior to 6 weeks. Your doctor will likely correlate this with your lab results. ...Read more

Genetic abnormality: You had an early fetal demise. This is fairly common and most often its a chromosomal (gene) abnormality during early development that is responsible. ...Read more

What is the risk of miscarriage after the heartbeat is seen on a 6 week ultrasound?

What is the risk of miscarriage after the heartbeat is seen on a 6 week ultrasound?

10-20%.: After your physician can identify limb buds and movements of the embryo your risk will decrease to less than 10%. It will be decreased even further (<1-5%) if your embryo grows well at the end of the first trimester (14 weeks). Take Folic Acid 1-5 mg daily and best of luck! ...Read more

I had an ultrasound and I am 6 weeks. They said I implanted low but the heartbeat was 122bpm. They also said that it was an abnormal embryo.what is it?

I had an ultrasound and I am 6 weeks. They said I implanted low but the heartbeat was 122bpm. They also said that it was an abnormal embryo.what is it?

Not Sure: To me , an abnormal embryos means it was genetically tested with PGD and found to have the wrong number of chromosomes. But one should not use that embryo. So maybe they mean the embryos appeared to be a lower quality embryos. You may want to ask them to clarify things. Your next ultrasound will provide more answers ...Read more

Ultrasound says my fetus is 6 weeks 2 days but my gestational sac is 7 weeks 2 days. Heartbeat is normal. Is everything ok?

Most likely: The most accurate measurement of the fetus is the crown rump length. The gestational sac is like a fluid filled balloon, not a perfect sphere. So the measurement of the sac can vary quite a bit depending on what part was measured. If there is already a fetal heart beat, that is a great sign. Keep your follow up appointments with your OB doctor. ...Read more
