Ultrasound shows gestational age 6w4days. Yolk sac present only. Should there be an embryo? Heartbeat?

Ultrasound shows gestational age 6w4days.  Yolk sac present only.  Should there be an embryo? Heartbeat?

7 weeks: I usually tell my patients that they should see cardiac activity at 7 weeks . The fetal pole is evident before that. You may want to do beta HCG levels 48 hours apart the change in these values can help answer some of your questions. ...Read more

Do I have a blighted ovum? Cramping, spotting, and back pain. 11 weeks no baby shows on ultrasound just a yolk sac.

Do I have a blighted ovum? Cramping, spotting, and back pain. 11 weeks no baby shows on ultrasound just a yolk sac.

We'll see: Your physician can tell you. If it is... The term "blighted ovum" is the wrong word to use in a disappointing situation like this -- i'd prefer the term "anembryonic pregnancy", because it reminds you that nothing magical happened, and that you can go on to be a mother. The placenta formed well & you were spared from baby having a terrible birth defect. I wish you comfort. ...Read more

Blighted ovum: At 7 weeks an ultrasound should show a fetus. The finding of only a gestational sac and yolk sac is unusual at the least and may suggest a blighted ovum. To be sure, most would recommend a follow up in a few days before discussing terminating the pregnancy. Hope this helps and all goes well. ...Read more

Early pregnancy: Ultrasound evaluation in very early pregnancy may not be conclusive. Not seeing a small fetus with a heartbeat may mean it is just too early or it also could be that the pregnancy is not growing normally. if there is no bleeding or pain then usually the healthcare provider will recommend repeat ultrasounds and sometimes blood tests to check pregnancy hormone levels. ...Read more

No yolk sac was found on ultrasound at 6w 4d. There was a strong heartbeat. Does this mean I will misscary?

No yolk sac was found on ultrasound at 6w 4d. There was a strong heartbeat. Does this mean I will misscary?

Not necessarily: While no one can really predict a miscarriage, the yolk sac is only meant to act as a food supply for the zygote during the very early stages of development. It should and will eventually disappear. Its disappearance does not increase your risk of a miscarriage. Hope this helps! ...Read more

What to do if I have been looking at other ultrasound pics and they all had a yolk sac but mine didn't from what I could tell?

What to do if I have been looking at other ultrasound pics and they all had a yolk sac but mine didn't from what I could tell?

Speak Up!: First of all, if you have a concern, you should speak with your physician. Your doctor does not know that you are looking at other ultrasound pictures and having anxiety about it. Anxiety is not good for any one. Maybe, your doctor does not wish to say anything yet, as there is no confirmation. He is trying to keep you away from stress. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects.

In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
