Question 1

Had ultrasound on 6 weeks , among three embryos, fetal pole, yolk sac is present in all, but heartbeat is seen in one only. is there any complication.

Accepted Answer

Possibly only 1 is viable
recheck ultrasound in 1 week to see if others have heartbeat.

Question 2

I am 5 months preggy and just had my ultrasound. it showed a male fetus. can it be possibly a female?

Accepted Answer

If there was clear evidence of male genitalia then it's a male. Sometimes it looks like one type of genders anatomy but the sonographer is not sure. So in these cases they might be wrong.

Question 3

Could an abdominal ultrasound at 8 weeks be off by a month (month further along)? fetus looks like a little bean & sac is still visible.

Accepted Answer

Better at 8 weeks is to have a vaginal ultrasound as they are much more accurate for dating pregnancies this early. A vaginal ultrasound should be off by at most, +/- 5 days, no more.  Definitely not a month.  Ultrasound is possibly more accurate at this age than is last menstrual period. If LMP and ultrasound differ by more than 5 days, doctors will use ultrasound to date pregnancy.

Question 4

Can a doctor mistake a fibroid for a fetus on an ultrasound? found fibroid which is new for me, but have been worrying for 2 months. negative hpts

Accepted Answer

Negative HPT supports the fact that you have a fibroid.

Question 5

What is the likelihood of miscarriage if the ultrasound notes the fetus is 'low in the uterus' at 2 months? any literature quoting a percentage?

Accepted Answer

All pregnancies are low in the uterus at only 8 weeks gestation prior to uterine expansion lifting them up into the fundus in the 2nd trimester.

Question 6

How a fetus age is known by ultrasound?

Accepted Answer

the crow-rump (head-bottom) lengths of the fetus and looking up from the chart, one can easily estimate the gestational age from fetal ultrasound imaging study.

Question 7

How many weeks can fetus ultrasound be seen?

Accepted Answer

Usually 5-6 weeks post date of last menstrual period (lmp).

Question 8

In what age we can distinguish sex of the fetus in ultrasound?

Accepted Answer

Sex is usually determined with confidence by 16 weeks.

Question 9

Can 13 week fetus be mistaken in ultrasound as a 9 week fetus?

Accepted Answer

Either your dates are off or there is something wrong with the pregnancy, at 13 weeks the margin of error is 5-6 days at the most either way.

Question 10

Can ultrasounds (2d, 3d and 4d) have an affect on a developing fetus? long term affects?

Accepted Answer

There have never been problems from ultrasound, either long or short term, demonstrated conclusively in humans. While it's impossible to guarantee zero chance, there have been many millions of ultrasounds on pregnant women with no convincing suggestion of risks. Recommendations are still to limit us exposure to medically necessary - so the boutique 'keepsake' ultrasounds should be avoided!
