If you have problems understanding and calculating your due date, check out and download a copy of the Ob calculator by York Winston. Hutchon’s site and the Gestation Network also provide pregnancy calculators. A large number of mails I received are about fetal anomalies, I have therefore tried to put together a Catalogue of Web pages which describe in some detail specific congenital anomalies that are diagnosable by ultrasound. You can visit the page here. I am pregnant for 7 weeks. I went for a scan yesterday and was told I should have a full bladder. They made me drink 4 cups of water and my bladder was almost bursting at the end of the session.
First trimester: weeks 1 to 12
Advertisement You at 4 weeks pregnant You might feel some pregnancy symptoms at four weeks, but there is every chance you will put them down to your period being about to arrive. Your boobs might have that ‘time of the month’ feeling, and you might even have some spotting or light bleeding. If you have taken a positive pregnancy test, you will need to follow it up with a visit to your GP as early as possible to get your booking appointment made with the midwife.
They will then book you in for your booking appointment with your midwife which is usually around 10 weeks. Things are getting real now!
For clues on what to do in this situation, we can only look to generalized macrosomia research and extrapolate.
Will I be given a risk level for any other abnormalities? What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. The amount of fluid is measured during a nuchal translucency NT ultrasound scan: That’s why the NT scan is used to help screen for Down’s syndrome.
Why might I have a nuchal scan? All pregnant women are offered an NT scan, to help assess whether or not their babies are likely to have Down’s syndrome. Every woman has a chance of giving birth to a baby with Down’s syndrome. The chance increases as you get older.
DIY alternatives to induction If you are desperate to see your baby, or are finding it hard to decline offers of hospital induction, then you may be considering ways to bring on labour yourself. There are plenty of links and suggestions on the UK Midwifery archives page on complementary therapies. It might be worth thinking through exactly you do not want induction in hospital. If you would not accept medical treatment to bring on labour, what is different about using complementary therapies?
Fine, if your intention is just to avoid hospital – but if you are concerned about interfering with your body’s ability to give birth, then DIY methods might not be right for you. If your baby is not ready to be born, in a difficult position , or your body is not ready to go into labour, then DIY induction might bring on a weak pre-labour which peters out.

When will I have my first scan? Share Becky Rutherford Midwife sonographer If your pregnancy is going well, your first ultrasound scan will be your dating scan, between 10 weeks and 14 weeks of pregnancy. Early scan An early scan is offered from six weeks, so before your dating scan. Your midwife or GP will only recommend an early scan if there’s a concern, for example, if you’ve had bleeding in this pregnancy. Your GP may also refer you for a scan if you’ve had a previous miscarriage.
Many hospitals have early pregnancy assessment units EPAUs that run daily. This means you can be referred for an early scan straight away, if needed. Your sonographer may ask to carry out a vaginal scan rather than one via your tummy. A vaginal scan can offer a clearer picture of your baby earlier in pregnancy than an abdominal scan. Your sonographer will gently put a narrow device called a transducer inside your vagina.
It shouldn’t be uncomfortable. The transducer will be covered with a plastic or latex sheath and will be well lubricated with gel. Rest assured it is safe for your baby. If you feel a bit apprehensive about a vaginal scan, you may feel less worried if you:
Nuchal translucency (NT) scan
I thought I was 7 weeks but baby measuring 5. According to my calculations I am 7 weeks along and the sonografer said that I’m 5. She told me to come back in a weeks time. I’m really worried now and praying that I will be ok. Has any of you ladies had a similar experience?????? Add message Report milk Mon Sep
The scans requires special probes and software to accumulate and render the images , and the rendering time has been reduced from minutes to fractions of a seconds.
Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.
The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus. Various ratios of the systolic to diastolic flow are used as a measure of this compromise.
The blood vessels commonly interrogated include the umbilical artery , the aorta , the middle cerebral arteries , the uterine arcuate arteries , and the inferior vena cava. The use of color flow mapping can clearly depict the flow of blood in fetal blood vessels in a realtime scan, the direction of the flow being represented by different colors. Color doppler is particularly indispensible in the diagnosis of fetal cardiac and blood vessel defects , and in the assessment of the hemodynamic responses to fetal hypoxia and anemia.
A more recent development is the Power Doppler Doppler angiography.
“Overdue” – but desperate for a home birth?
Can the scan show the gender of my baby? Examples of ultrasonography you may see used during your pregnancy. Most parents look forward to their scan because it gives them the first glimpse of their baby. You will probably be give you a printout of your baby by the sonographer as a keepsake, it is important to remember the main purpose of the scan. It is not to provide the first photo for your baby album, or to find out your baby’s sex.
It is to check that your baby is growing and developing normally.
I was sent to a specialist for a more advanced sonogram and told that nothing is wrong other than the polyhydramnios.
Can the scan show the gender of my baby? What is actually done? Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. The whole pregnancy will be assessed. The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself. The baby will be measured, and the anatomy examined in detail.
It is recommended that all pregnant women have a scan in the first trimester at around 12 weeks of pregnancy to confirm their dates. First trimester ultrasonic scans may show ‘soft’ markers for chromosomal abnormalities, such as an increased fetal nuchal translucency back of the neck to enable detection of Down’s syndrome fetuses. When is the nuchal fold screening test carried out? The test is performed between 11 weeks and 13 weeks 6 days into your pregnancy.
The test cannot be performed outside this time frame as certain features that need to be seen on the scan are not present. If you are unsure of your period dates or have an irregular cycle, we suggest that you contact your doctor, midwife or health care provider as early as possible to arrange for a dating scan. There is no hard and fast rule for the number of scans you should have during pregnancy.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them. Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing.
However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to have these prenatal tests, even though the tests are often difficult to interpret.
Imagine a sperm coming together with an egg to develop into a fetus.
Prior to the 18th century, caring for pregnant women in Europe was confined exclusively to women, and rigorously excluded men. The expectant mother would invite close female friends and family members to her home to keep her company. The presence of physicians and surgeons was very rare and only occurred once a serious complication had taken place and the midwife had exhausted all measures to manage the complication.
Calling a surgeon was very much a last resort and having men deliver women in this era whatsoever was seen as offending female modesty. However, the subject matter and interest in the female reproductive system and sexual practice can be traced back to Ancient Egypt  and Ancient Greece. Living in the late first century A. After the death of Soranus, techniques and works of gynecology declined but very little of his works were recorded and survived to the late 18th century when gynaecology and obstetrics reemerged.
These advances in knowledge were mainly regarding the physiology of pregnancy and labour. By the end of the century, medical professionals began to understand the anatomy of the uterus and the physiological changes that take place during labour. The introduction of forceps in childbirth also took place during the 18th century. All these medical advances in obstetrics were a lever for the introduction of men into an arena previously managed and run by women—midwifery.
Ultrasound – Sonogram
Dating and viability What is a dating scan? A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Dating scans also reveal other important information such as:
Brigett English’s first baby, Oscar, was born at home 20 days after his due date.
In fact, it stems from something I noticed way back in August of last year. Steve has a total of 6 connections, none of which are 2nd or 3rd degree connections with any of mine, he lives an hour away from me and is in a completely different industry. However, she has only one connection on LinkedIn. So just because we share a last name, we might know each other? Heather happens to be a girl I dated way back in high school. The only problem is, this person is the wrong Heather.
This Heather has a different profession and lives on the other side of the country. This is the maiden name of my aunt who was married into the family years ago. This person lives across the country and has zero connections. In other words, if someone searched for both of us, we might know each other. Herman follows me on Twitter, but happens to live in the Netherlands. Doug lives in New York and contacted me through my personal site a year ago.
We exchanged a couple emails and that was it.
