Ultrasound said babys belly was smaller than head what does this mean?
I had the same thing happen during my ultrasound today and am looking for answers.
Why are some chicks hatched with their yolk sac stil attached?
Left over or unused nutrients. This will drop off as does the umbilical cord on a mammals new born.
When can you find out baby's gender?
It depends on the determination method. More invasive laboratory tests can tell you within a couple of months pregnancy. Ultrasounds would give an indication within 4 months or so. The "old fashioned method" of inspecting the crotch can be used as soon as they are born. All the methods have their shortcomings, which could include fetal harm (during amniocentesis) or making the wrong determination.
Does the uterus continue growth after a fetus dies?
The uterus grow to make room for the fetus. A fetus that doesn't grow - no growth of the uterus.
If you get an x ray can you see a fetus?
You shouldn't have x-rays when pregnant since they can damage the foetus. However, when the foetus' bone have formed you would be able to see it.
This has been a controversial question an embryo is like the puzzle for a human it puts it together and a hormone does this so no it is not really human, it just creates one.
Is it possible for baby to be alive even if no heart beat is detected during an ultar sound?
If you were still very early on in pregnancy, then yes there is still a good chance that everything is fine. Many ultrasounds don't show a heartbeat until 7 weeks. Everyone is didn't, some people will see the heartbeat at 4 or 5 weeks, while others don't see it until 6, 7 or even 8 weeks.
What is a healthy weight to have a pregnancy?
I don't think there is a healthy weight but im sure being overweight by alot is not healthy, or underweight by alot.
Why does Baby has no stomach during ultrasound?

Does a woman's tummy get hard at three months of pregnancy?
My fiance is about 3 months pregnant, and we were wondering the same thing. So we brought the question to our OBGYN. He told us that this early in the pregnancy, the baby is behind your bladder, which is right above your pubic bone. We were looking in the wrong place. Perhaps you are too? When we felt there, it was the answer we were looking for :)
this is my second pregnancy an my tummy is hard and round but this was not the case the first time i didnt show till about five months gone
Where are babies in a womans body?
The baby is in the womb, which is basically in the lower half of her stomach.
In the fetus the opening between the two atria is called?
The Foramen Ovale or Oval Window it's the opening between the two Atria, window is covered by a flap of tissue that is a vavle.
It is a
protein on the tip of the sperm cell that interacts with oocyte integrins on the plasma membrane to allow fertilization to occur.
This interaction triggers the zona reaction. -This is a calcium dependent reaction that causes cortical granules to be released into the pervetrilline space to prevent polyspermia (fertililization by subsequent sperm cells).
If you are 32 weeks pregnant yet measure at 29 weeks does this mean you have IUGR?
I measured small too. But I had a scan and it was fine the cause for my smaller than daes bump ws that the baby was low down in the pelvic region.
I don't think so. At 31 weeks, i measured 27 and now at 35 I measure 32. my doctor says it's just the way my body is. So stay calm and listen to your doctor. everything will be ok.
It is very true that it all depends how you carry your babies and if you were smaller the whole way through. Even if it drops off a little and remains consistently smaller than it is "supposed to be", it doesn't mean there is anything wrong. If there is a problem it also does not mean they will be IUGR. I have amniotic fluid problems and with three pregnancies I dropped off in size, they watched me, did NST's, AFI's, etc.... and although my kids were induced early because of amniotic fluid levels.... they are 8, 6, and 18 months and doing great! Do not worry unless they tell you to.
The external "tape" measurement of your tummy is just a tool used as as a rough "watchdog" measurement, if you will allow the use of this phrase. It your measurements are +/- 3 cm from your dates...assuming your dates are reliable...then the "watch" goes on. If the measurements begin to trend one direction or the other from the +/- 3 cm "norm"....an ultrasound review will be done. Like has been said, it may just be things like fluid amounts, genetic size, baby's position during the external measurement, etc....and not baby falling behind in its literal growth. Good question...!
ANSWER
Briefly, YES, measuring smaller during pregnancy than expected is IUGR by definition. However this might be caused by innocent causes, such as carrying low as discussed above.
This site gives a good brief and plain language description of IUGR and possible causes:

What the period between development of the fetus between fertilization and birth?
It is the gestation period.
What is the normal volume of amniotic fluid at 37 weeks?
On average, the normal volume of amniotic fluid at 37 weeks is about 1000 mL or 1 L (34 fl oz). While this volume can vary significantly from one pregnancy to another, during late pregnancy a volume of less than 400 mL (13.5 fl oz) is called oligohydramnios; more than 2000 mL (68 fl oz) is called polyhydramnios.
