My Twin Pregnancy Experience

Twins are quite a phenomenon but many people are unaware of the different types of twins.

When we received the news, the first thing I learned were the different types and how my pregnancy would be affected by my twin type.

There are 5 different types of twins.

First: fraternal twins. That is when the mother releases 2 eggs at the same time and they are both fertilized. These types of twins run in families because the trait of releasing 2 eggs at the same time can be passed on from mother to mother. These twins are not identical because they have 2 different eggs, which means 2 different sets of DNA.

Second: identical twins with 2 separate amniotic sacs and 2 separate placentas(Di/Di). Identical twins happen from one fertilized egg splitting. When the identical twins have 2 separate placentas, it means they have split on day 1-3 after fertilization.

Third: identical twins with one placenta and 2 amniotic sacs (Mono/Di). This is the twin type that the girls were. Their fertilized egg split between days 4-8.

Fourth: Identical twins that share one placenta and one amniotic sac (mono/mono). Fertilized egg separated between days 8-13

Fifth: Conjoined twins (also identical). They partially separated between days 13-15

My pregnancy was considered high risk (all twin pregnancies are) so I saw an OB and had many ultrasounds to make sure the babies were growing at an even rate.

If there were to have been a significant change in size between one baby and the other, it would have been an indication of Twin to Twin Transfusion Syndrome (TTTS), where one baby is taking more blood from the placenta, leaving the other baby with less blood.

My girls ended up having a very minor case of this. Kayley took more of the blood and Sophie got less, making Sophie pale and Kayley quite red, for the first month of their lives. There was also a half pound weight difference—Kayley had more of the weight. Sophie had to be on an IV for half a day to help get her hemoglobin back to normal.

Taking care of myself

I read the book When You’re Expecting Twins, Triplets, or Quads: Proven Guidelines for a Healthy Multiple Pregnancy by Dr. Barbara Luke, Tamara Eberlein, and Dr Roger B. Newman and it gave me great advice on how to have a healthy twin pregnancy. It gave a weight chart on how much weight you should gain according to your BMI and gave tips on eating and activity level.

I learned that I should eat about every hour—this really helped me avoid nausea as well.

Side note: I am very lucky to have very minimal nausea when I’m pregnant. I also believe that I was able to feel less nauseous this pregnancy because I was at home pretty much full time, so I was able to have small meals more frequently.

I also learned that it is more important to avoid a lot of activity with twin pregnancy (I know—it’s the opposite of what they tell you for a singleton pregnancy). Because your body is already doing much more than it should be, it’s important to take it easy. In the later months, I found it too difficult even to walk 10 minutes to the park with Elijah. So I drove. It seemed ridiculous to me but at least that way, I was able to play with Elijah once we got there. I was able to carry Elijah up the stairs to bed the entire pregnancy, thankfully, with no problems. I continued nursing Elijah until the girls were born as well.

But there were times where I would sweep the floor and pick up a few things and then my energy would pretty much be spent for the majority of the day. There was a time where Elijah spilt apple sauce on the floor and I teared up a little because I didn’t have enough energy to clean it up. So it stayed on the floor until Dan got home.

Basically, I listened to my body and never overdid it because I wanted to keep those babies cooking for as long as possible.

Strange twin pregnancy things:

I would bring Elijah into his bed every night after feeding him and my pelvis would crack. It was unsettling. And uncomfortable.

If I had energy/motivation to make dinner, I would sit on our bar stool beside the counter so I wouldn’t have to stand up while prepping (standing more than 10-15mins was painful).

My nails started to get really brittle. At my next doctor’s appointment, my OB told me that I was very low on iron. So I started taking iron supplements.

Overall, I was very lucky to have a very calm pregnancy compared to what some twin moms experience.

Can’t wait to share the birth story next week! Miraculously I lasted until 37 weeks and had to be induced. See you back next week with more details.
