Didi means diamniotic/dichorionic
Ie two sacs and two and two placentas

Yep. It seems that about 25% of monozygotic (identical) twins are di/di. This happens when the egg divides very early, and each bub develops his own sac and own placenta. (See the Degree of Separation section of this Wikipedia article: https://en.wikipedia.org/wiki/Twin).

All dizygotic (fraternal) twins are di/di except in very rare cases.

However, it seems very common for doctors who are not very familiar with multiples to assume di/di equals fraternal. It will be a fun surprise at birth either way!

Basically its a way of referring to 2 placentas and 2 sacs, Dichorionic-Diamniotic x


Sorry didn't see everyone elses reply - doh

My OB was insistent that our boys were fraternal as they were in 2 seperate sacs, even though there was one placenta.

When I went to a specialist at 18 weeks for an anomaly scan, I was told that because they were both boys, because there was one placenta, because they have the same calcification (soft marker) in the same place, and because the membrane seperating the sacs was less than 2mm wide, they were identical.

hiya ..i dont have twins but am an Auntie to twin monkeys!

they where fraternal..two sacs etc and were told they not identical..but its hard to tell them apart! i posted a pic for you! there is slight differances..but my brother still gets them confused!! Men for you!!

I have just recently had twin girls, they are non identical as they had seperate sacs and placentas, but when we lay the together they look very similar. The only differences really is their hair (one has slightly more and darker hair) and that one has a tiny bit chubbier face.

My girls were DCDA, does anyone know what that means?

DC=Dichorionic and DA=-Diamniotic x

Hello,
My twins were in separate sacs and are identical. Before birth I was told they were most likely fraternal, however, once tested after birth it was determined they were identical.

Yes ! This happened to me. Told they were frats blah blah and through this site my suspicions got raised and had my girls tested and they are identical.
Edit: just noticed this is donkeys old !

The last few posts are recent, so I'm sure it will be helpful for some people. Especially as doctors are so vague about dcda twins. I'm waiting on results at the moment, literally no idea what the result will be.

 

[marymoomin]

Good luck - keep us posted. When do you expect to hear?

 

[cherrylips100]

I sent the swabs back three weeks ago so hopefully in the next couple of weeks.

This is so weird seeing a post I started being replied to. Mine turned out to be non identical, but as I sit outside their bedroom door trying to convince them to goto sleep, they are definitely identical pains in the butt x x
