Is 2mm a normal nuchal translucency at 13 weeks pregnant?

Is 2mm a normal nuchal translucency at 13 weeks pregnant?

See below: The short answer is yes, it is within normal. However, it is a bit more complicated than that. The nt is one factor in assessing the risk of having a chromosomal abnormality. If you are 22 years old with an nt of 2 mm, you would get a different risk than a 45 yr old with an nt of 2 mm. There are other factors as well and the data is combined with blood work. ...Read more

Done 3 urine tests. positive. about 4 weeks pregnant. Vaginal ultrasound scan shows embryo but with no yolk sac. Endo thickness: 19.3mm. Worried?

Done 3 urine tests. positive. about 4 weeks pregnant. Vaginal ultrasound scan shows embryo but with no yolk sac. Endo thickness: 19.3mm. Worried?

Give it time: Our technology to detect pregnancies is amazing but sometimes we see structures well before they get formed. Give it time for the sac to form structures; you can repeat the US in 1-2 weeks to assess growth. This can be correlated with hormone level checks as well to ensure appropriate rise Best Wishes Dr M ...Read more

Ultrasound showed a gestational sac of 9 wks. Fetal pole not clearly visualized corresponding to 8wks 3 days, unable to detect fetal heart motion. ?

Repeat: The difficulty visualizing the fetal pole and heart beat at 9 weeks could be a result of the quality of the ultrasound. A repeat ultrasound and/or serial quantitative HCGs would help to clarify what is going on. Hope this helps. ...Read more
