Ultrasound scans in pregnancy may be routine or they may be offered for pain or bleeding or due to problems in previous pregnancies.
There are two ways to perform an ultrasound scan.
in early pregnancy, especially before 11 weeks, usually to have (internal) trans-vaginal scan, where the probe is placed in the vagina. This gives a clear picture and most accurate in early pregnancy. It can also be offered after 11 or 12 weeks if the trans-abdominal scan does not give a clear enough picture.
Of the 11 or 12 weeks, including in the booking-scan routine, it is more common to have a trans-abdominal scan. People who spread a special gel scan on the lower abdomen (below the navel and above the pubic hair line). He then moves the scanner over the gel, sometimes pressing, until the uterus (womb), and pregnancy can be seen.
If you do not want trans-vaginal scan, you can request a trans-abdominal scan. Which can provide some information about your pregnancy, but it is less clear than the internal scan and that might delay the diagnosis.
There is no evidence that having vaginal or abdominal scan will cause a miscarriage or harm the baby. If you bleed after vaginal scan, it will most likely be because there is a higher pooled blood in the vagina and probe dislodged it.
An ultrasound scan may be able to detect pregnancy and heart rate in normal pregnancy about 6 weeks, but this varies widely and is usually not recommended. All too often, a scan at 6 weeks showed very little or nothing, even the perfect pregnancy develops, while waiting for a week or 10 days would make the findings more clearly.
Most pregnant women referred to their first routine (or reservation) ultrasound scan somewhere between 11 and 14 weeks of pregnancy. The purpose of the scan are:
Some women may be offered a nuchal scan between 11 and 14 weeks. The purpose of this scan is to try to detect multiple chromosomal abnormalities, such as Downs syndrome.
Many hospitals also offer further anomaly scan at 20 weeks, making a more detailed examination of the baby's development.

Unfortunately, sometimes the scan showed that the baby had died, perhaps a few weeks earlier and often unmarked -sign or symptoms such as bleeding or pain. This is often called a "miss", "silent" or "delayed" miscarriage. This may come as a surprise that is quite large and may take some time before you can take this information in.
You also may have to make some tough decisions about how to manage the process of miscarriage. You can read more about this
You may be referred for an initial scan because of vaginal bleeding or spotting, or perhaps because you have problems with a previous pregnancy.
The best time to have a scan is from about 7 weeks gestation when it should be possible to see the baby's heartbeat in a normal pregnancy. But it would be difficult to detect a heartbeat in early pregnancy and in those cases it would be difficult to know whether the baby had died or not developed at all, or whether it is just smaller than expected but still growing.
for that reason, you may be asked to return for another week scan or later. At that point, people who scan will be looking for a marked difference in the size of the gestational sac and the baby develop and heartbeat.
Sometimes, it can take several scans before you know sure what happened. It can be very stressful to deal with this uncertainty - some women describe as "in limbo". You may need to find some support for yourself if this happens to you.
If the scan does not take a snap and the baby seems to be the right size according to your date, it can be very convincing, even if you are still bleeding.
among women with a history of recurrent miscarriage has shown that those who see the heartbeat at 6 weeks gestation have a 78% chance of pregnancy progresses. It also suggests that seeing the heartbeat at 8 weeks increase the chances of pregnancy continues to 98% and at 10 weeks rose to 99.4%.
The figures may be even more positive for women without previous miscarriages.
So things can go wrong and sadly they sometimes do, but as long as there is a heartbeat, the risk of miscarriage decreases as the weeks go by.
In some cases, if there are no signs of pregnancy in the womb, you may be given a blood test and may be asked to return two days later for a retest.
This blood test measures the levels of pregnancy hormones ßhCG. In normal pregnancy develops hormone levels double every 48 hours and if the pattern is different, this may help to identify what happened in pregnancy.
If there are no signs of pregnancy in the womb and you have symptoms suggestive of an ectopic pregnancy, you are more likely to have blood tests and investigations called laparoscopy, which is done under general anesthesia. You can read more about this in our leaflet

In all these situations, the pregnancy will be fully miscarriage with time, but there are several ways to manage the process. You may be offered a choice, or a hospital may make recommendations.
