Our team plus a mono/di question
It's official, we are Team Blue again, times 2!!!!! Time for Mommy to get used to the idea of a house full of boys, cuz we are soooo done after this 
I also have a question about mono/di ID twins. We've had 3 ultrasounds now, the earliest at 9 weeks. And all three times she has been almost positive that we are mono/di, but she refuses to say it's 100% the case. So for those of you who are mono/di, is this a 100% thing for you, or a likely scenario? How do they know for sure that you are mono/di? Is my tech just being super conservative? I'm so confused!

Re: Our team plus a mono/di question
They weren't 100% sure with my mo/di girls either.
If there's one placenta, they are mo/di. The problem is, it can be difficult to see how many placentas are there, and also they can fuse later in pregnancy.
Originally my tech thought she saw 2 placentas at 14 weeks. At 18 weeks they said one, and were unsure then if it fused. The big giveaway was how difficult it was to find the membrane. It was very thin, which is an indicator for mo/di twins.
Ultimately, we knew for sure after I delivered. The lab at the hospital analyzed the placenta and my doctor told me the day after the girls were born that it was just one placenta.

We've been told it's definite. You can see the thin membrane in between, and they keep saying it's "definitely one placenta."
I know sometimes it's hard to see if it's one placenta or two fused.
It's WEIRD to see the membrane move as they move, isn't it?? Sometimes we can't see it on the u/s and it looks like htey're just attacking each other.
What's even more Weird to me is how strong that tiny little membrane must be. I mean, you'd think one of them could kick right through it, especially toward the end, but they won't.... just another example of the amazing things our bodies do!
Oh Lord. I remember sitting through all of my anatomy scans and irrationally worrying as I watched the screen that B was going to poke through the membrane as she reached toward's A's face. I was certain she was going to poke her in the eye.
I had my first u/s at 10w6d and my OB told us there was one placenta and we could see a very thin dividing membrane, which I soon found out meant mo/di. This was confirmed by my MFM at my a/s at 18 weeks. We never had a question about it. I did some research on how they can tell. Apparently it is easier to determine chorionicity by eariler u/s. di/di has a thick dividing membrane and the look of two separate sacs, also google "twin peak sign". mo/di looks like one big sac with a thin membrane and no twin peak sign. If you don't have an early u/s then it's harder to differentiate between one placenta or fused placenta. Here's my first u/s:

Congrats on the boys!
We discovered our mono/di twins at 8 wks 1 d, so it was easy for the tech to see the shared placenta and we were lucky to find the separating membrane right away. And we've had it confirmed at every u/s since then, so there has never been a doubt for us.
Congrats!
We're having mono/di girls. We didn't have any ultrasounds until 20 weeks and the doc was hesitant to confirm that there was just one placenta. When we visited the MFM a few weeks later, he said due to the thinness of the membrane, and some other factors, he is positive they are mono/di.
Congrats on your boys. I think a house full of boys sounds like so much fun.
I'm mono/di and they were 100% but I also did an IVF and only transferred one embryo so we were pretty darn sure
