Getting a twin pregnancy is a surprising and happy moment for many mothers. Generally, twin pregnancies can be seen if you have an ultrasound from the fifth week of pregnancy.
However, this is not absolute because it is influenced by several factors, ranging from hormonal factors to the equipment and type of ultrasound used. In some cases, pregnancy cannot be detected or is known as hidden twins.
So, what exactly are hidden twins and how can this happen? Come on, read this article to the end to find out the answer according to medical advice.

Get to know the condition of hidden twins
Hidden twins is a condition when twin pregnancies are not detected through the ultrasound process. This condition causes pregnant women not to know that they are pregnant with twins because the ultrasound results only show one baby.
This condition usually only occurs early in pregnancy when the fetus is still small. As time goes by and the size of the fetus increases, the possibility of hidden twins will become smaller.
Hidden twins usually will not cause any harm to the mother and little one in the womb. However, if twin pregnancies are discovered early, mothers can definitely prepare themselves more and take extra care in maintaining the pregnancy.
Things that cause the condition of hidden twins
According to Healthline, there are several things that cause hidden twins to occur. Here are some of the causes that you need to know.
1. Doing an ultrasound too soon
When you feel signs of pregnancy or get positive results from a test pack, mothers usually rush to have an ultrasound and hope the results are very accurate. In fact, according to some experts, the earlier an ultrasound is performed in early pregnancy, the less accurate the results will be.
This is because at a very early gestational age, usually only the fetal sac is visible. Even if the fetus is visible, its size is still very small and if a twin pregnancy occurs it will be more difficult to detect.
It’s a good idea to do another ultrasound when the gestational age is around 10 to 12 weeks. If the fetus is not visible from the ultrasound results, further examination needs to be carried out because there are concerns that undesirable things will happen.
“Another more serious thing that causes the baby not to be seen on an ultrasound is because the baby’s development is less than normal and can lead to miscarriage or ectopic pregnancy,” said Amanda Williams, obstetrician and gynecologist, as reported by Baby Center.
2. Babies share the amniotic sac
In twin pregnancies, the babies usually have their own amniotic sacs. However, in some cases there are also fetuses who prefer to share the amniotic sac with their twin sibling.
When fetuses share the amniotic sac, the risk of hidden twins increases. This is because one of the babies could hide behind its twin and make it invisible during the ultrasound.

3. The equipment and type of ultrasound are not good and not precise
Another factor that can be said to be an external factor in the occurrence of hidden twins is that the equipment and type of ultrasound used is not appropriate. It could be that the ultrasound equipment used at that time was faulty so it could not detect twin pregnancies.
Another possibility is that the type of ultrasound used is not appropriate, for the first ultrasound you should do a transvaginal ultrasound. The reason is because with transvaginal ultrasound the results are more accurate even though the size of the fetus is still too small.
If you know you are pregnant with twins, it is very important to take extra care of your pregnancy. There are several things you should not do if you are pregnant with twins. What are these things?
