The baby files are no longer secret! And we hit our first goal. 12 weeks! Just about 1/3 of the way there…seems surreal.
By now your baby weighs a full half-ounce, with a crown-to-rump length of about two and a half inches — about the size of a large plum. It’s hard to believe (especially from the outside, since you’re probably barely showing at this point), but your baby has more than doubled in size during the past three weeks.
This week marks a turning point for your baby. At 12 weeks pregnant, the herculean task of developing new bodily structures is nearing an end, as most of your baby’s systems are fully formed – though there’s still plenty of maturing to do. Now comes the maintenance phase, during which your fetus’ systems continue to mature for the next 28 weeks and the organs get to work. For one thing, the fetal digestive system is beginning to flex its digestive muscle — literally — as it starts beginning to practice contraction movements, a skill your baby will need after birth to push food through the digestive tract. The bone marrow is busy making white blood cells — weapons which will one day help your baby fight infection once he’s out of your safe haven (including all those germs passed around the snot-nosed playgroup). And the pituitary gland at the base of the brain has started producing the hormones that’ll enable him (or her) to make babies of his (or her) own babies in a couple of decades or so.
Here is the first official bump photo!
Not so big in the morning but by 8:00pm…whoa. It’s big. My uber slow digestive tract is contributing to the bigness, which is really annoying.
Ultrasound – 11w6d
The first ultrasound I’ve ever had where I got to keep my pants on!
Lima Bean – 4.9 cm long, measuring 11w5d, HR 153
Butter Bean – 5.5 cm long, measuring 12w1d, HR 167
*For those of you needing a little help with the acronyms…cm=centimeters; w=week; d=day; HR=heart rate.
Aren’t our babies beautiful?!?! Hands down, this was one of the coolest things I’ve ever seen! And yes, I know things just get way cooler from here. Those little beans were flipping and flopping all over the place. We got to see their little arms and legs and spines. Butter bean had her legs crossed, which now makes me believe she’s a girl! I just love them so much…
So let’s talk a little bit about our whole twin situation for a minute. I’ve been getting some questions so I’m hoping this helps.
Our twins are not identical. Identical twins (or Monozygotic twins) occur when a single sperm and a single egg hook up and form a blastocyst. This “blast” then splits in two, creating 2 separate embryos. Identical twins will always be the same sex. Obviously.
That did not happen with us. Our RE indicated that, due to my age and other factors, the likelihood of multiples was very low. He suggested we transfer 2 of our little “blasts” for the greatest chance of a successful procedure. We all know how that turned out. Of course these “blasts” could have split once they were transferred, leaving us with 4 babies (or more!). But not to worry, we have confirmed that did not happen! Whew!
So our twins are fraternal (or dizygotic). They each have their own placenta, which is providing them all of the blood and nutrients they need. And in my case, the placenta is posterior. This means it’s attached to the back of my uterus and I should be able to feel the babies move sooner than later. If the placenta is in the front (and in front of the babies), it can take longer to feel them wiggle.
* A friend pointed out that it’s possible that one of the blasts we transferred could have split while the other didn’t stick. I hadn’t even thought of this possibility but considering their are two separate sacs and two placentas, I’m guessing that didn’t happen.
How I’m feeling
95% of the time…I’m feeling pawesome (that’s for you RB!). I don’t know how I escaped the first trimester without morning/all day sickness but I am so lucky that I did! It’s still lights out by 9:30 but the daily fatigue is pretty much gone. No aches or pains (yet), no headaches, no heartburn.
Round ligament pain is picking up, but it’s still not terrible. I’m having major digestive issues (i.e. nothing is happening) and that’s making me bloated and uncomfortable. My whole ribcage is expanding (including the boobs) and I’m finally going to bite the bullet and buy new bras. But if that’s all I have to complain about, I’m way ahead of the game.
Jerry is his usual amazing self. He puts up with my grouchy mood swings and takes care of business when I go to sleep at 9:00. He’s a peach.
