MoMo, MoDi, DiDi – what does this all mean?

Posted on

Since the day we found out we were having twins, I did the worst thing you could ever do for your brain and your insecurities about pregnancy, Google!

Actually it wasn’t all bad news that we read. Most of the information we read from sites like:

http://en.wikipedia.org/wiki/Monoamniotic_twins

http://www.monoamniotic.org/

http://multiples.about.com/od/medicalissues/a/MoMoTwins.htm

http://www.pregnancy-info.net/monoamniotic.html

were very informative and helped us understand the situation we were in.

From the picture of our babiestwins ultrasound, we learned from the doctor there was a risk involved with our pregnancy. If the twins shared the same sac and placenta or in medical lingo Mono amniotic-Mono chorionic or in short MoMo twins.

Amniotic – Sac
Chorionic – Placenta

Many sites and blogs I came across showed many beautiful delivered MoMo twins and from what I read, there is one unique fact about MoMo twins, they’re always or 99.999% identical babies. Not so much like Brandon and Brenda from my favorite TV show in the 90′s, but more like the Winklevoss twins from the movie “the Social Network.”

Sadly, there are increased risk with this type of pregnancy, but I won’t go into the details here. If you really want to read more, feel free to visit the above links.

Identical twins don’t only happen in a MoMo pregnancy, but also in a MoDi one. MoDi or Monochorionic-Diamniotic, means two sacs but one placenta.

These twins are identical as well because of the way the egg splits after fertilization, but just form a separate sac for each baby. Compared to MoMo, MoDi has less risk because of lower chances of umbilical cords getting tangled.

Brandon and Brenda type twins are referred to as DiDi twins or Diamniotic-Dichorionic. Meaning the babies have separate sacs and separate placentas. This pregnancy can produce a boy/girl, boy/boy and girl/girl combination. Probably with the least amount of risk of the twin pregnancies, DiDi twins have less complications.

Here’s a nice little picture from wiki that explains a lot.

Our doctor didn’t want to confirm what we had yet till later ultrasounds. So all we could do was continue our positive thinking and hope for the best. So with learning this news, we decided to purchase a book to get some guidance on what we needed to do to give these kids the best possible chance out there. We purchased When You’re Expecting Twins, Triplets, or Quads: Proven Guidelines for a Healthy Multiple Pregnancy by Barbara Luke from Amazon.

On a side note: Regardless of what you read and what you hear from others, please keep positive. I always remember the “life is like a box of chocolate” quote from the movie Forrest Gump, but I always like to add that if all you can think about is crap being in that box, you’ll never be able to enjoy the chocolate when you see it. This is an awesome moment in your life. Enjoy it. And if you’re in the same shoes as we are, it’s still too early to say anything is for sure.

So now with enough medical knowledge, it was time to tell our families.


I knew it!!

After we saw the positive test results, my wife made an appointment to verify the results with the doctor. Unfortunately, the earliest appointment conflicted with a work commitment and I was unable to make it. The doctor was able to confirm what our home pregnancy test showed us.

My heart continued to jump for joy while my mind braced it for whatever may be coming our way.

Unfortunately, we weren’t immune to the sad stories of couples facing heart aches as they tried to start a family. Some of these stories were very, very close to us. We cried for our friends when we found out what they were going through. So you can imagine the thoughts running through my mind.

So like any pregnancy, we were scheduled to go for the first ultrasound on week 10. It was week 7 according to her last menstrual date, a week after we found out. My mind was saying, “oh shit, three freaking weeks.” I just really wanted time to fly by faster. I was trying so hard not to start planning in my head, things like how we would tell our families, which room the baby would have, how we were going to afford raising a family, or how I would have to take time off work. It seemed like a million questions running though my head everyday and every hour. So I tried very hard to continue our daily routine and tried extremely harder to not get caught up with my wife’s joy and excitement for our possible new addition to the family. In many instances, I remembered telling my wife, ” let’s live with this news day to day and of course keep it quiet.” That lurking possibility of heart ache was there everyday till that day on week 10, August 25th.

I left work early to pick up my wife and we headed to our appointment in Pasadena.

When we arrived at the doctor’s office, couldn’t help but notice that it was a nice calm waiting room occupied by a couple of very noticeably pregnant women. After about 20 minutes, we were walked into the ultrasound room. My wife changed into the gown provided and we sat there and waited.

About 5 minutes after, the doctor walks in, introduces himself and begins the ultrasound. I glanced at the ceiling and noticed a printed signed saying “RELAX.” I know it wasn’t meant for me, but I took a couple of deep breaths after seeing it.

So I stared at the screen intently. Not really sure what I was looking at, I waited for something to appear. The first words I hear from the doctor are ” do you see what I see?” I looked so hard and saw the most amazing thing I have ever seen in my life. twins ultrasound

On the screen I stared and saw the two little fluttering heartbeats, as a few seconds past and I realized what he had just said. I shouted these exact words,”I knew it!!!”

As the doctor continued to do his thing, he took baby A’s heart rate. 142bpm and then taking baby B’s. 135bpm.

twin A heart beat

twin B heart beat

After seeing the most amazing thing ever, I heard the most amazing thing ever. My babies heart rates.
