Ultrasound of the pregnancy sac but not yet found the embryo is a phenomenon that makes many pregnant women worried. So where is the cause? Should this be a sign of miscarriage? Let's go to find answers to these concerns.
The process takes place in the formation of the fetal sac and embryo
To understand why an ultrasound has a fetal sac but has not yet seen an embryo, you first need to know about the development of the fetus in the womb. After fertilization, the eggs will take 7-10 days to move into the uterus and nest.
Embryo formation process from 12 to 14 days or longer depending on the location of the pregnant mother
Then, the sac starts to form before the embryo can attach roots to the uterine wall. Depending on the mother's situation, the process can take place quickly or slowly, from 12 to 14 days. Around week 5 of pregnancy the HCG levels are up to par and at that point the embryo can be seen with an ultrasound.
The causes of an ultrasound have a pregnancy sac but have not seen an embryo
According to research, there are many causes of having a pregnancy sac but not seeing an embryo on ultrasound. In which, popularization can be mentioned as:
Signs of miscarriage
Ultrasound of the fetal sac, but the embryo has not been found with symptoms such as bleeding, abdominal pain, the cause may be due to miscarriage . At this time, the pregnant mother should quickly go to the hospital to perform other tests. Depending on the actual situation that the doctor will prescribe different treatment options.
The embryo has not been seen because of the wrong fetal age
As mentioned, the time required for fertilization and implantation of an egg is 7-10 days. However, in some people this can last up to 12-14 days. In addition, determining the exact date of fertilization is quite difficult. Therefore, displacement of gestational age is possible.
When an embryo cannot be found in an ultrasound scan, the reason may be that the mother had an early ultrasound. You can wait for more and repeat the ultrasound as directed by your doctor. Don't worry too much at this stage. Instead, pregnant mothers should rest and keep comfortable to avoid affecting the baby's health.
The test is wrong so it is impossible to have an embryo
The principle of the pregnancy test is based on the concentration of HCG in the urine. If HCG reaches enough concentration, the stick will show 2 bars. This proves you are pregnant. However, in some cases, due to expired sticks, incorrect tests or impure urine, false pregnancy confirmation results.
Sometimes the pregnancy test is wrong
In addition, some drugs, such as drugs, also alter HCG levels. Therefore, although the test strip shows 2 marks, but at ultrasound, the embryo cannot be found. It means that you are not pregnant.
Mother pregnant outside the uterus should not see the embryo
This is a quite dangerous phenomenon for pregnant mothers. The fertilized egg does not move inward, but implants outside the uterus. During an ultrasound, the doctor cannot see the embryo in the amniotic sac.
The most common manifestation of ectopic pregnancy is black discharge, dull pain in the lower abdomen. When detecting this condition, women should immediately see a doctor to handle it promptly. Waiting for a long time will endanger the health of pregnant mothers.
Pregnant eggs
This is the phenomenon in which the cells that nourish the fetus grow too fast. They prevent the umbilical capillaries from keeping up and causing edema. The edematous placenta will gradually degenerate, forming a fluid sac and occupying an area of the uterus.
This situation is very dangerous for pregnant mothers. Late detection can cause bleeding, abdominal bleeding and deep penetration into the uterine muscle. However, this phenomenon is also relatively rare. Ideally, you should check carefully for timely treatment if you unfortunately get pregnant with eggs.
What should pregnant mothers do when an ultrasound has a pregnancy sac but has not seen an embryo?
During pregnancy, if there are signs of abnormalities in the body, you should promptly go to the hospital. After an ultrasound with a pregnancy sac but no embryo is found, your doctor will perform an intensive test. This will help to draw the most accurate conclusion.

Next, you need to follow your doctor's instructions and instructions exactly. Pregnant mothers absolutely do not use drugs that doctors do not specify. At the same time, you should also choose reputable clinics such as major hospitals.
The mother's psychology will greatly affect the fetus. Women should note that too much stress can also cause miscarriage, especially at the stage when the fetus has just started to form.
Ultrasound of the pregnancy sac but no embryo is found to occur for many reasons. Ideally, pregnant mothers should follow the instructions of a doctor. This is how to help protect the health of mother and baby.
