I had an U/S last week as I had no idea what my dates where because I never got my period back after DD. To our surprise we are having twins. I was 6weeks 5days. Both were measuring the same and had strong heartbeats. I asked the sonographer if he could tell if they were identical or fraternal but he said it was too early to tell but did say they are quite far away from each other. Since doing a bit of research it seems many people find out about this stage if they are fraternal or identical. I would suspect they are fraternal as I'm assuming because my body hadn't ovulated in close to two years that it spat out two eggs at once. I'll get the report back this arvo so will know a bit more then but just wondering what others think? It doesn't really matter really just curious but the type of twins they are will also determine how my pregnancy is managed.

Congratulations on your twins, that is lovely news :)

The short answer is, that you won't know if they are fraternal or identical until you find out their sex (if their sex is different) or until they are born, and possibly DNA tested. I'll explain below.

In utero, we don't describe pregnancies as fraternal or identical, we describe their placenta and amniotic sac. One type of twins is dichorionic-diamniotic (di/di). These twins each have their own placenta and sacs. This is the 'safest' type of twin pregnancy and can also be called a "fraternal" pregnancy, however, that label is not necessarily accurate. Identical twins can have this type of pregnancy (mine did).

Another type of twins is monochorionic-diamniotic (mo/di). This is where your twins share a placenta but they have their own amniotic sacs. This type of pregnancy is often referred to as an "identical" pregnancy. This label is mostly accurate.

Then you can have a monochorionic-monoamniotic (mo/mo) pregnancy. This is where the twins share both placentas and the amniotic sacs. This is the riskiest type of twin pregnancy and as far as I know, they are always identical. They are also 75% likely to be twin girls!

To answer your question, I think it's a bit early to tell. The report may give you more information though? The placenta is not fully formed yet. You need to see the placentas and sacs when they are fully visible to tell what type of pregnancy you have. As for identical or fraternal...if you find out the sexes and they are different, they will be fraternal. If they are the same sex, and it's a di/di pregnancy, you will need to wait until they are born to tell.

Congrats! I found it all very confusing too.

I am having fraternal twin boys (Di/Di) and at my 7 week ultrasound the boys were clearly in two black blobs of their own, although we were told at this stage it was difficult to tell.

They are very far apart but they do look like they're sharing a placenta (from my very limited experience) and could be identical.

They'll be able to give you much better info at the 12 week scan when everything is clearer!

The beginning of your pregnancy will be managed the same as singleton (although you will likely see an obstetrician rather than midwives and you will need ultrasounds roughly every month- I'm 27 weeks and have had 5 so far). Things will likely change at 30 weeks, maybe earlier, depending on their growth and if they are indeed sharing a placenta... I expected to be treated high risk but I've found it's all very low key, again you might have a different exp if they are sharing a placenta.

Also wanted to add they can still be identical if they are in their own placentas, it all depends on when the embryo split, but it is more likely they're fraternal.

Enjoy- it is so special!

Thank you both for taking the time to answer my question. I should have mentioned I'm a midwife so do know a bit about twin pregnancy but not about ultrasounds. In Australia we don't use the terms Mo/mo mo/Di or DI/Di to describe twins. At least not in any of the hospitals I've worked in, I think that's American. We use MCMA, MCDA and DCDA.

I've just got given the report and turns out I am having either MCMA or Mcda twins so they will be identical. Will know more at the next scan. Crossing my fingers they have their own amniotic sac.

I can't believe how anxious I am since finding out we are having twins. I'm so scared I'll lose one or both of them and wish I could have weekly scans just to ease my mind.

I'm feeling so blessed to be having twins but just hope everything is ok.

The anxiety doesn't stop until about 20 weeks! Sounds like you'll have some great networks to help you through this time. Congrats on your identicals- boy 💙 Or girl 🎀 Is the next exciting bit!

Side note, all my paperwork says Di/Di and I'm in Sydney so maybe it varies fro. Hospital to hospital 🤷🏻‍♀️

I had what I think was Di/Di (non-identical) boys and they were in seperate sacs etc. It appears you have one sac? I don't think they really know for certain until they test?
