All Fraternal (non identical) twins are Dichorionic but the reverse is not true all the times. A small percentage of Dichorionic twins can still be identical. Monozygotic (identical) twins, which form when a single zygote splits into two, can also be dichorionic, depending on the timetable of the split. If it is early, within a few days after fertilization, two separate blastocysts will implant independently, resulting in dichorionic-diamniotic (di-di) twins. Only about thirty percent of monozygotic twins fall into this category. Whether your twins are identical or not, you will know only after they are born. If one is a boy and other is a girl, obviously they are non identical. If they have different blood groups, they are non identical. If they are the same sex and have same blood group then there is a possibility that they are identical. You either have to wait for them to grow and observe their features or do a DNA analysis of both to confirm! Many congratulations on your twin pregnancy and all the very best.

Non identical

It means two sperm fertilized two eggs so,they ve their own placenta and r not Identical twins

As they are diamniotic dichorionic they are nonidentical twins
