After 60 days of pregnancy, pregnant women can see two gestational sacs when doing B ultrasound, the fetal head is large and small, the fetus has a fetal heart, fetal buds and fetal heartbeat pulsation.
In the case of identical twins, ultrasound B will show two fetal heads, separate torsos and limbs, and so on.
If it is a fraternal twin, because it has two fetal sacs, it is necessary to wait for the embryo to appear fetal heartbeat and fetal bud, that is, it takes about 9 weeks for the fetus to begin to develop before the twins can be clearly distinguished.
Even if they are identical twins, there will be differences in ontology.
