Hello Eky Kusuma, thank you for your question
Congratulations on your pregnancy. In general, twin pregnancies can be divided into two, namely identical twins and non-identical twins. Identical twins occur when one sperm cell fertilizes an egg, and when cell division occurs, two cells of the prospective fetus with the same genes are formed, so that they generally have the same sex and the same face.
Whereas non-identical twins or fraternal twins occur when two sperm cells fertilize two eggs. This is why in external pregnancy there is a chance that the sex and physical form are different from each other, because the twins' genes come from different sperm and egg cells.
To find out for sure whether a woman has multiple pregnancies, an ultrasound examination can be performed (ultra sonography). With this examination it will be seen how many fetuses and placenta are formed. in identical twin pregnancies, two fetuses usually develop in the same uterus, whereas in non-identical twin pregnancies, there are two fetuses with two placentas to each other.
Measuring the height of the fundus or the top of the uterus is not a standard test to determine whether there are multiple pregnancies. This examination aims to estimate gestational age and fetal weight (in singleton pregnancies).
