Pregnant. About pregnancy Week by Week, ultrasound, weight gain - and early fetal scanning in 3D / 4D
Using modern technology and a special ultrasound technique can provide three-dimensional ultrasound images of the fetus, where you can clearly see the fetal facial features. Recordings can be stored and played on CD-ROM, DVD and VHS. When 3D images are displayed live formed 4D, that is, with movements so that you can keep up with what the child is doing in the womb, with the same depth and impressions as for 3D scanning. 4D scanning means that you see the fetus move while being scanned with 3D. Investigation is always outside the abdomen. - Read the bottom of the page about pregnancy week by week.
When made 3D/4D scan is best?
The best time for 3D/4D scan around week 26 to week 34 and the best time is week 28 to week 32, because at this time is much amniotic fluid in relation to how much the child turns. After 34 weeks decreases amniotic fluid volume and it will rarely manage to get good 3D/4D shots, there are considerable differences in amniotic fluid volume and therefore can still perhaps succeeded. By scanning between 13 and 17 weeks, you could see all the baby on the screen. If the child is located deep in the womb can supplement with vaginal 3D/4D scan. The child still has a very embryonic-like appearance. After 17 weeks, you could not see the whole child on the screen, because it now has become too big. You see, therefore, the child in "fragments." The longer you go in the pregnancy the more similar to a newborn child.
Early pregnancy scan
Early ultrasound scanning can already after 5 weeks see a pregnancy in the uterus if pregnancy is normal developed. After 6 weeks you can see a tiny fetal heart beat. One can see a fetal heart beat, when the fetus is only 2 mm long. If pregnancy length is safe and can not be seen a fetus in the uterus after 6 weeks, to be feared that the fetus has not developed. When you can see a heart beat can also count the number of fetuses. It is therefore premature to see if the pregnant woman to have twins or just one child. Approximately 2 percent of all pregnancies are twins. Once you've seen a fetal heart beat by ultrasound scan, the risk of miscarriage small. In many pregnancies ending with abortion, there has never been brought a fetus. Therefore it provides extra security to be scanned early. Scanning in the first weeks of pregnancy is always at vaginal scanning. By ultrasound scan before 12 full weeks, you could not see developmental defects in the fetus.
Boy or girl - or maybe twins?
After 10 weeks is enough DNA from the fetus in the pregnant woman's blood to find out if it's a boy or girl who is coming. The blood sample can not be taken earlier, the amount of fetal DNA is modest in the first weeks of pregnancy. At an early ultrasound scan found that the stage of pregnancy and that there is life. You can also explore whether there is a single child or maybe more. In a twin pregnancy, one can not examine the gender of each child, but you can see if the pregnant woman must have 2 girls or whether at least one fetus is a boy. The test for measurement of fetal DNA in the pregnant woman's blood is the new techniques very safe. Fetal DNA tested only for sex. The test is not designed to test for diseases.
Child size can be calculated
Based on scanning the child's size is calculated. Here you measure the head width and length, belly size and the length of the femur, and from these calculate a target weight of the child. From 24 weeks also calculated fetal weight and can be compared with normal weight for her age. It is also possible to measure the 'flow' the cord. This means that the pregnant woman can hear the heartbeat and you can see if the baby is getting enough nourishment and amniotic fluid volume can be assessed and it can be examined where the placenta lies. After week 30, you can determine whether the baby will become very large at birth. Children with high birth weight is already at that time great children.
On ultrasound, and scanning of pregnant
Ultrasound is sound waves that are sent out of the scanner head and then sent back as echoes, which are translated into images. Studies have shown that ultrasound with the frequencies and the strength used in pregnancy scans are harmless. The technique is specially designed for example to perform pregnancy scans in traditional 2D and 3D and 4D. The scanner is connected to a flat panel so that you effortlessly live can follow the investigation closely. Several factors affect the quality of scanning images such as the distance between the scanner head and the child, why uterine location, intestine and adipose tissue may be a contributing factor to image quality. The child's posture in the womb is also crucial. Furthermore, it can be an advantage if the pregnant woman's bladder has not emptied one hour before the scan, since water in the bladder may also increase the quality of scan images. - Click to read the MRI and CT scan >>
Pregnancy Week by Week
The average pregnancy lasts 40 weeks from last menstrual period, or 38 weeks from fertilization. That is about 9 months or 270 days. Pregnancy period is divided into three trimesters, when the first trimester is the first 12 weeks of pregnancy, second trimester from 12 weeks to 28 weeks and the third trimester the remainder of the pregnancy. - Development:

About the weight gain during pregnancy
Weight gain in pregnancy is individual. The average weight gain is 10-15 Kilogram. A number of factors affect weight gain. In the first part of pregnancy will be as pregnant often take a little, but can also go down a little in weight. Nausea and decreased appetite are not uncommon in the first trimester. After 12 weeks is a steady increase in weight of 200 to 800 grams per week normal. - Typical weight gain trimester (part):
- Part 1: is from 0-12 weeks, where appropriate to a weight gain of 1-2 kg
- Part 2: 13-28 weeks, where appropriate to a weight gain of 3-400 g per week
- Part 3: is from 29 to 40 weeks, where appropriate with a gain of 1 to 3 kg per month
A weight gain of 10-15 kg is regarded as normal for a pregnant woman who waits one child. Taking as a pregnant more than 600 g of each week, you should contact your doctor or midwife to uncover the cause. The figures below are Health authorities recommendations and applies pregnant, waiting one child.
Less than <18.5
Between 18.5 to 24.9
More than >25
Between 14-15 kg
Between 10-15 kg
Between 8-10 kg
Where does the weight gain from?
The baby, before birth weighs about 3,500 grams: The uterus grows to approximately 900 grams. Amniotic fluid is approximately 800 grams. Placenta weighs about 650 grams. Blood volume increases by approximately 1,250 grams. Breasts typically grows by about 400 grams. Fatty deposits under the skin around 1,700 grams. Swelling is typically about 2,000 grams. That is, overall, an increase in weight of 11.2 Kilogram, as a normal weight gain for a pregnant woman. Weight gain in pregnancy is individual depending on weight and BMI before pregnancy.
