Fetal development by ultrasound
Common Questions and Answers about Fetal development by ultrasound
fetal-development
20 mm Fetal heart rate: 164 bpm, the other one is 33,7 X 18,4 Fetal length: 16,7 mm
Yolk Sac: 5,9 mm Fetal heart rate: 166 bpm
Also embryon1 age is 10w3d but embryon 2 is 9w2d. I'm very concerned. Are those differences ok?
The next ultrasound is in 10 days and the wait is killing me.

Classification and external resources
ICD-10 G93.0
ICD-9 348.0
Choroid plexus cysts (CPCs) are cysts that occur within choroid plexus of the brain. The brain contains pockets or spaces called ventricles with a spongy layer of cells and blood vessels called the choroid plexus. This is in the middle of the fetal brain.
I had an ultrasound done at what I thought was 5 weeks 5 days and a yolk sac was seen but no fetal heart or fetal pole seen, and a repeat ultrasound to be done 10 days from then. Is this normal to not see any fetal pole or heart at this stage? The ultrasound tech said she wouldnt put me at 5 weeks 5 days.
i had my doctors appointment today the doc afformed me i was 6wks 3days today at the time of my first ultra sound i was approx 5wk 5days no heartbeat only yolk sak and development begfining so the doc said this was normal and heartbeats are usually detected in wk six or even wk seven the nurse tried to say there may only ever be a yolk sac and no bub but the doc and the lady who performed the ultrasound said no heartbeat or fetal pole can be normal at the early stage of five wks now im confused
Sorry to hear this. I had never heard of this and did some research. This is what I found. Hope it helps and prayers for you && the little one :)
CPCs can form within this structure and come from fluid trapped within this spongy layer of cells, much like a soap bubble or a blister. CPCs are often called "soft signs" or fetal ultrasound "markers" because some studies have found a weak association between CPCs and fetal chromosome abnormalities.
m 6 weeks pregnant at the moment and i thought everything was going find until i got a call from my hospital telling me they needed to schedule me for an earlier appointment because when reviewing my ultrasounds they saw a problem with the fetus development. does anyone have any idea what this can mean? I would really appreciate it if you can help.
Usually the 5th week you will see the gestational sac but maybe no fetal pole. By week 6-7 you should see the fetal pole and if you're lucky a heartbeat. By week 8 you should get a heartbeat. So if you are only 5 weeks it sounds like your development is very good seeing both a fetal pole and hb. Did he mention what the heartrate was?? I am not sure what the "likely" fetal pole means because if there is a heartbeat then there is definitely a fetal pole there!!
Week 6 - Gestational Age (Fetal age 4 weeks)
5 ½ to 6 ½ weeks is usually a very good time to detect either a fetal pole or even a fetal heart beat by vaginal ultrasound. The fetal pole is the first visible sign of a developing embryo. This pole structure actually has some curve to it with the embryo’s head at one end and what looks like a tail at the other end. The fetal pole now allows for crown to rump measurements (CRL) to be taken, so that pregnancy dating can be a bit more accurate.
Breathing in the Womb
Babies do not actually breathe in the womb---at least, not in the usual sense. Fetal lungs are not fully functional, and are not even able to fully expand, until after birth. During the later stages of gestation, the fetus may "practice" breathing by inhaling and exhaling amniotic fluid. The fetal lungs do not process the amniotic fluid, the way fully formed lungs process air, but experts believe this "breathing" is important to fetal lung development.
How common it is for early ultrasounds to be off in the first trimester, and how much? Doc wants to do one more checkup. My dates don't work so we've spent the last couple weeks trying to determine how far along I am. If I go by last bleed as LMP, I should be 7 and 2, but yesterday's ultrasound showed the sac measuring 5 and 4, and just a hint of fetal pole. No clear pole or hb yet. (Another post explains the whole story.
i went in and they said according to my last menstral cycle i was 7 wks... then i had an ultra sound and it showed me being only 5 wks and no sign on an emryo so i went back 10 days later and the ultra sound showed me being 6 wks 3 days and there was an embryo as well as my babys heartbeat! so... im guessing you are just right at 6 wks if you are even that far bc my dr said you wont see a heartbeat until atleast 6 wks 3 days and possibly not even that soon!!
I can tell you, From experience that a baby's heart is fully developed by week 18, which is why doctors do fetal echos between 18-24 weeks, it's the soonest they can visualize the heart without the bones getting in the way or "shadowing" it, and also the latest for them to detect holes and other issues.
There are many cases when a baby has a hole or two early on and as the baby grows and the heart continues to grow the holes close or get smaller on their own.
Don't worry it's still early. At my 4 week ultrasound they saw a small sack & nothing else. 5 weeks they had a hard time seeing the yolk sac until the lead person did my transvaginalsound. 6 weeks they saw the sac, yolk, & tinyyyy baby with slow fetal pole. 8 weeks they did a regular ultrasound & saw a baby and saw fetal pole. Heard heartbeat when they did a transvaginalsound to hear it. However my doctor said I was lucky to see anything at 6 weeks. So you maybe 5-6 weeks.
2010 my HCG read 2,000 and a sac and fetal pole together with fluttering fetal heartbeat (!) could be seen on a transvaginal ultrasound. I was pretty sure on that day I was 6 weeks and 1 day, however, the doctor said the size of the sac and the rate of the heartbeat was more like that of aprrox. 5 weeks. I am scheduled for another scan in 2 weeks but am, of course, worried waiting.
They did an ultrasound and said there was a gestational sac of 5wks and no fetal heart pulse. Is it normal for things to be so off?
Fetal Pole (6 weeks)
A mass of fetal cells, separate from the yolk sac, first becomes apparent on transvaginal ultrasound just after the 6th week of gestation. This mass of cells is known as the fetal pole. It is the fetus in its somite stage. Usually you can identify rhythmic fetal cardiac movement within the fetal pole, although it may need to grow several mm before this is apparent.
The fetal pole grows at a rate of about 1 mm a day, starting at the 6th week of gestational age.
From wikipedia-
During embryological development, some fetuses may form choroid plexus cysts. These fluid-filled cysts can be detected by a level II ultrasound (18–20 weeks gestation). The finding is relatively common, with a prevalence of ~1%. Choroid plexus cysts (CPC) can be an isolated finding, which confers a 1% (variable based on population studied) risk of fetal aneuploidy. The risk of aneuploidy increases to 10.5-12% if other risk factors or ultrasound findings are noted.
There is feeble faint heartbeat with fetal development, but doctors are concerned as the baby din show any progressive growth since last 1 week. Only the fetal pole has started showing more prominently. I am very worried. This is scary as i had a spontaneous abortion in only 5 weeks few months back. I wont be able to take a second blow. Request you to give some insight. I have been given a week to observe. I want it to happen.
Sounds like the growth of baby is progressing normally, the only thing I hadnt heard of either was the "tail". Below is a complicated quote that mentions the growth and then regression of the "tail" during early fetal development. Do you have a follow-up US to monitor things? Your HCG levels and observation of HB are very encouraging.
"the rostral neuropore closes and develops into the forebrain prominence and then the head.
in the afternoon she did the ultrasound again for the heartbeat which she saying that its very low n fetal development is slow as it show that its 5 weeks 6 days n she said its not possible that our measurement is wrong so for sure its going towards miscarriage n she said we have to monitor your body till there is a heartbeat as i have no spotting or bleeding yet.
I had a repeat done on 05/12/2013. That ultrasound showed a yolk sac with no fetal pole. By 05/17/2013 there was fetal pole... no heartbeat. Heartbeat was first seen 05/21/2013 (that is when I was given the due date 1/15/2014). On 07/05/2013 i had my 1st trimester screening and the CRL was 68.5 which put me at 12.6 weeks. So everything seems to add up.
So I was scheduled another ultrasound today I should be 8 to 9 weeks since lmp we seen a larger sac, about 8 weeks 3 days, a shadow of a yolk sac, but nothing else. No heartbeat. No signs of a fetus or fetal pole. After the first ultrasound, I was told there was not enough development to determine viability. Again, 10 days later, same story, but sac growth. I just want to see if anyone else has dealt with something like this.
