After a few weeks of pregnancy, the ultrasound can be seen, after a few weeks of pregnancy, it is possible to go for an ultrasound, what should be prepared for the first ultrasound and how is the ultrasound schedule for the whole pregnancy?
The presence of the fetal sac through ultrasound, especially when compared to the corresponding levels of HCG levels, is a useful way of identifying pregnancy as well as helping to detect ectopic pregnancies. or abnormal defects right from the start.
In early pregnancy , transvaginal ultrasound (a technique that uses high-frequency sound waves exposed through the vaginal opening) is much more accurate than abdominal ultrasound.
The pregnancy sac is usually the first sign of pregnancy on an ultrasound. At about 5.5 weeks, doctors can see the yolk sac inside the pregnancy bag. If a transducer ultrasound is performed, the chances of the pregnancy sac can be seen a week or two earlier, when the mean diameter of the pregnancy sac is 2 to 3 mm.
In cases of successful conception, transducer ultrasound can detect the pregnancy sac at 5 weeks of age. Now the level of the hormone hCG when it reaches about 1500 to 2000.
It's been 5 weeks since your last menstrual date, but if a woman's hCG level is so low, the pregnancy sac is likely to be invisible. This means that you ovulate late and your pregnancy is less than 5 weeks old. Your doctor may order the ultrasound again in a few days or a week after that.

Yolk sac
Gestational sac
If the 5-week ultrasound does not have a fetal heart , the mother should not be too worried because the embryo is probably swimming back into the uterus.
Usually, the heart rate will be more pronounced from the 7th week of pregnancy if the mother is healthy and has a normal pregnancy. However, it is not until 12 weeks that the baby's heartbeat can be active, at this time, the mother can also feel the baby's heartbeat directly in her womb.
If your hCG level is higher than 1500 to 2000 but there is no imaging of the pregnancy sac, your doctor can usually diagnose you as likely to have an ectopic pregnancy.
The main reason an ultrasound is performed during early pregnancy is to ensure that the fetus has entered the uterus, and helps to rule out an ectopic pregnancy causing slow rise in hCG, uterine bleeding. or cramps. However, these conditions may be the result of other more serious causes such as a miscarriage, so your obstetrician may ask you to have more in-depth tests.
Conversely, if the ultrasound shows a fetal sac or fetal polarity (possibly heartbeat) appearing in the fallopian tube, this is the best evidence for an ectopic pregnancy.
An ectopic pregnancy is when an egg is fertilized, but not implanted in the uterus as usual, but in the ovary.
If not caught early, ectopic pregnancy can become a life-threatening threat for both mother and fetus, especially if the fallopian tube breaks down or other conditions are more serious.
However, it is difficult to recognize signs of ectopic pregnancy by the usual way (vaginal bleeding, shady abdominal pain, ...). At this time, the medical methods through ultrasound will work, namely:
Ultrasonic transducers
How to do an abdominal ultrasound
An intrauterine abdominal ultrasound combined with hCG levels can help your doctor think about an ectopic pregnancy.
In the vast majority of cases, finding out you're already pregnant in the womb means you're not at risk of an ectopic pregnancy. Just imagine this, you could be pregnant both inside and outside the womb.
This is called a heterozygous pregnancy and is actually a twin pregnancy with one embryo implanted in the uterus and the other in the fallopian tube.
Several studies have found that the risk of ectopic or heterozygous pregnancy may increase with women undergoing in vitro fertilization.
Therefore, if you have to become pregnant according to the method mentioned above, the pregnant mother should be monitored and screened to avoid the risk of a heterozygous pregnancy.
Starting your pregnancy journey is also a series of days of happiness, anxiety and anxiety. Early diagnosis of pregnancy can lead to insomnia when you don't see the pregnancy sac. But do not hesitate to talk to a specialist, at the same time check your menstrual cycle accurately, wait a few more days and combine monitoring for signs of pregnancy to ensure the best of the development of the fetus.
