Dichorionic Diamniotic (DCDA) twins - Identical or Fraternal?
We were told very early on that the type of twins that we were having were Dichorionic Diamniotic (DCDA) twins. We were also told at our very first (6 week) scan that our twins were identical.
Future doctors and ultrasound technicians told us that our twins were fraternal. For the first few months, we would explain that we had been told right at the beginning that they were identical and were told time and time again that no, they were definitely fraternal.
Because they had their own sac and own placentas.
I did quite a bit of Googling of this type of twins and found that:
* They were the safest type of twins you could have.
* Although the majority of DCDA twins are fraternal, 10% will be identical
They may or may not have separate (or fused) placentae
The girls' placentas were on the back wall of my uterus so an ultrasound could not truly see whether it was fused or not.
