Fetal gender screening by ultrasound at 11 to 13(+6) weeks.
In Sweden, an average of slightly more than two ultrasound examination during the first half of the pregnancy predicts the delivery date with greater precision. was dismayed to learn that my first ultrasound won't be until the 18th (! . is an emergency of if they think that you are large/small for dates. Ultrasound departments of Ultragyn, Stockholm, Sweden. When the expected date of delivery was postponed after ultrasound dating by 7 days or . Slow fetal growth between first and early second trimester ultrasound scans and risk of.
The traditional view, here as well as in the US, is that the due date is at 40 weeks and pregnancy should last no longer than 42 weeks. Now a new study is challenging whether having a due date is helpful at all. A study by the US National Institute of Environmental Health Sciences has found that the length of pregnancy can vary naturally by as much as five weeks.
Try telling this to your midwife in the UK, where every woman is expected to give birth within a strict two-week window or face medical intervention. The rest are either premature or late. For parents faced with the latter, this new study is a revelation. The arrival of a baby is something that needs to be judged on a case-by-case basis, taking into account the health of the mother and baby, plus the mother's birth record, instead of setting arbitrary dates which are not based on sound evidence.
Getting an ultrasound before 18 weeks?
If you fall beyond the week limit, you are strongly encouraged to be induced when labour is started artificially.
One in five babies are induced in the UK, and many women choose to undergo it long before the week cut-off. But it carries risks, however small. There is an increased risk of forceps or vacuum extraction, an increased risk of caesarean section and an increased risk to the baby of jaundice.
I faced the decision of whether to induce at weeks with my third baby, Jack, now nearly three. Our two older children had been born naturally, 10 days and 14 days overdue. Those days of waiting are excruciating. With every day that passes, you become more and more convinced that there is something wrong with your baby. I still can't help but worry that something is wrong.
My concern is that a birth defect undetected by a sonogram may still be a possibility and that the doctor may be keeping something from me. He is reluctant to do an amniocentesis. It seems that they want to give me as little information as possible and I can't help but wonder why if everything is o.
A detailed ultrasound examination at 33 weeks should be able to diagnosis most, if not all the recognizable causes of polyhydramnios. A significant proportion of pregnancies with polyhydramnios does not have any demonstrable birth defects in the fetus. An amniocentesis may indeed be helpful for planning necessary treatment but your doctor probably felt that the chance of finding something wrong with the amnio is too small to warrant doing it.
That is actually good news. I don't think your doctor is trying to keep things away from you. My doctor said that my baby's head is a little 'smaller than dates' whereas the limb bone and the abdomen were quite on par with dates. Does that reflect that I have a baby with an abnormal head? If this is your first scan, then it may be a problem with dates.
If your dates have been quite well validated from a previous scan, then it appears your baby could have a slightly smaller head. All of us has a different size head, isn't it? And mind you, your doctor measures the side-to-side 'diameter' of the fetal head and if your fetus has a relatively 'flatter' head it will appear 'smaller' on measurement. This may simply reflect the head's configuration rather than anything that you should be alarmed about. It will need a size lag of up to weeks before one would start to consider malformations such as microcephaly small head syndrome.
I had a scan at 8 weeks and my doctor said the fetus is only 7 weeks, and it was because I had irregular menstrual cycles. I had another scan at 34 weeks and my doctor now said the fetus size was only 31 weeks. Should I stick to the earlier scan or should I use the later scan to fix my Due date?
If my fetus is smaller, would it be wise to leave it in the womb for as long as possible so that it can grow bigger and get more mature? You should always use the result of a scan that is done earlier on in pregnancy for 'dating' purposes as it will be more accurate. In the later part of pregnancy the measurements will be affected by growth variations and will no longer reflect the fetal 'age' correctly. In your case, the findings apparently indicated that you have a smaller than average baby.
It is incorrect logic to think that babies who are not growing well should be left inside the womb for a longer period of time.

In fact the reverse should be true. The baby may be better off outside than in and for this reason we sometimes have to deliver these babies well before the actual due date. I had a scan at 34 weeks.
My doctor said the estimated weight of the fetus is 2. Is this too small? How much should an average baby weigh at 34 weeks? The weight for an average size fetus at 34 weeks is about 2.
We would say a baby is small-for-dates when it's weight is below the 10th percentile line, and in the case of 34 weeks this will be 1. Please take a look at the Intrauterine weight chart. Your baby is on the small side, but not too small.
You must also know that estimating the weight of the fetus with ultrasound measurements sometimes can incur errors of over 10 percent. Your doctor will usually make an assessment together with other ultrasound findings. I will have a scan tomorrow. What is the chance that I would be able to see the sex of my baby on the screen?
I really do not want to know this before the baby is born.

The chance that you will recognize the genital organs of the baby without any prompting is very small. Interpretating an ultrasound image requires a lot of training and skill and is not like looking at a photograph of a person taken in front of him. Patients are often unable to 'see' the parts of the fetus the doctor is actually carefully studying during a scanning session. A friend of mine was seen at the ER because of pain. She was pregnant for about 7 weeks.
They did a scan and found no sac in the uterus and asked her to go home. Two days later she was admitted again to another hospital with massive bleeding from an ectopic pregnancy.First Ultrasound with a completely NEW Due Date! - Word Wednesday
Why was this initially missed on the scan? Ectopic pregnancyis notorious for not being diagnosed early, as the physician has always to exclude basically 3 other conditions in early pregnancy which give rise to pain. She can have pain for no apparent pathology in early pregnancy, probably as a result of of uterine and venous engorgement.
Missed or inevitable abortion. Ruptured ovarian cyst or pain arising from other abdominal organs. Ultrasound, unfortunately, will not be able to make a 'definitive' diagnosis of ectopic pregnancy in most of the cases as it is often not possible to visualize the actual gestational sac in the fallopian tubes. The fact that there is no gestational sac seen in the uterine cavity may just mean that the pregnancy has not been growing normally or that some sort of an abortion might have occured or that the pregnancy, due to to an irregular menstrual cycle in the woman, is much less advance than is thought.
The doctor often needs to take into account of the menstrual history, the time she had a positive pregnancy test, the intensity of the pain, physical signs, a blood count and findings on ultrasound scan. I would appreciate any information on molar pregnancy that you can provide. Last year I had emergancy surgery done because of this condition.
I was told very little information about it at the time. I was wondering specifically: Again, any information on previous studies of this condition is appreciated. I am afraid I won't be able to give you detailed descriptions about a specific disease.
