Vegetables that contain Vitamin B12, do they exist?

A pregnancy sac or gestational sac must be owned by every woman who tests positive for pregnancy. Pregnant women can see this sac since they have an ultrasound for the first time, namely when the pregnancy is around 5 weeks old.  

One ​​of the signs that a woman is really pregnant is the detection of a gestational sac during an examination ultrasonography (ultrasound). This gestational sac forms around 5-7 weeks after the last menstruation. The formation of a gestational sac accompanied by other pregnancy symptoms are signs that a woman is pregnant.

Function of the Pregnancy Sac for the Fetus

When undergoing an ultrasound examination to confirm pregnancy, pregnant women's obstetricians may mention the gestational sac. So, actually, what is a gestational sac?

The gestational sac is a sac that contains the embryo and amniotic fluid. At the beginning of pregnancy, this sac appears in the middle of the uterus with a diameter of around 2-3 mm and will enlarge as time goes by. If seen through an ultrasound examination, this sac appears white with a clear center. 

Well, the gestational sac itself has a very important role, namely:

1. Protects the embryo

One ​​of the main functions of the gestational sac is to protect the embryo or prospective fetus during the development process span>. Thanks to the gestational sac, the fetus can avoid injury and infection. 

2. Provides nutrition for the embryo

Inside the gestational sac, there is also a yellow sac (yolk sac) that surrounds the embryo. This sac provides nutrition to the embryo and helps in the production of red blood cells during early pregnancy. That way, the embryo will be able to develop normally and smoothly until it becomes a fetus in the future.

3. Produces pregnancy hormones

In early pregnancy, the gestational sac will form a placenta. In the gestational sac, the placenta that is starting to form will produce the pregnancy hormone, which is called human chorionic gonadotropin (hCG). This hormone can be detected through a pregnancy test with testpack. 

So, when the testpack results are positive, this also means that the gestational sac has formed and the woman can be declared pregnant. 

If the gestational sac is not visible    

Even though it is one of the early signs of pregnancy, it is not all gestational sacs were visible from the first ultrasound. There are several causes that make the gestational sac invisible, including:

Too quickly do an ultrasound examination 

When you first have an ultrasound and you can't see the gestational sac, don't panic, pregnant women. It could be that the date calculation for the ultrasound examination is not accurate, so that pregnant women cannot see the gestational sac during the ultrasound. 

So, if an ultrasound examination is done too early, this will usually mean that the gestational sac has not been detected, because the stage of development of the embryo and gestational sac is still too early.

If this happens, the doctor will usually schedule another ultrasound examination a few weeks later to confirm whether or not there is a gestational sac. 

Ectopic pregnancy 

Another reason why the gestational sac is not visible even though a proper examination is carried out in the 5th week is an ectopic pregnancy. Ectopic pregnancy occurs when a fertilized egg attaches and grows outside the uterus. 

This condition is characterized by vaginal bleeding or pain in the pelvic area. If not treated immediately, an ectopic pregnancy can risk causing heavy bleeding and endangering the safety of pregnant women.  

Early miscarriage (chemical pregnancy)

Not seeing the gestational sac during an ultrasound examination can also be caused by early miscarriage. Usually, this condition is accompanied by continuously decreasing hCG levels as well as vaginal bleeding and stomach cramps.    

Apart from the gestational sac not being visible, there are also conditions where the gestational sac is empty when an ultrasound examination is carried out. The gestational sac was visible, but there was no embryo inside. This condition indicates that the fetus has failed to develop.  

Failure to develop in the fetus can be caused by abnormal cell division, chromosomal abnormalities in the fertilized egg, as well as infections, autoimmune diseases, or endocrine disorders in pregnant women.     

That's everything about the gestational sac. Please remember, the gestational sac can only be seen with an ultrasound examination. So, if pregnant women have received test pack results positive and want to confirm whether there is a gestational sac, immediately schedule a pregnancy check-up with a doctor, OK?  

Pregnant women can consult a doctor via online chat if you experience symptoms of pregnancy, such as nausea, vomiting, dizziness, stomach cramps, or aches.
