Risky Business

I had another ultrasound on Wednesday, this time with the perinatologist.  Because perinatologists really only deal with high risk patients their ultrasound machines are lightyears ahead of some OBs. My OB is in his mid-60s and his machines are reflective of that.  So, while my OB can tell me that I am having two babies, my perinatologist can tell me that I am having two girls and that their bladders are the same size. Also, both of their hearts have four valves!

I have now entered a period of very high levels of monitoring.  I see my perinatologist every other week and my OB every third week for the next 6-8 weeks.  Lots of time in the stirrups.  At my perinatologist this week I learned a bit more of why I am having such extensive monitoring.  There are two main reasons.

  1. My cervix. For those of you who don’t know (and apparently have never seen a hospital drama) a closed cervix means no babies are coming out any time soon, at least not vaginally.  An open cervix means baby time.  When they talk about 10 centimeters of dilation, that’s the cervix. It is basically the entrance to your uterus. With multiples, you are at a higher risk of your cervix opening prematurely, well before it should be baby time.  We are talking months early. So, every two weeks they check the length of my cervix, starting this last Wednesday.  I am pleased to report, in the words of the doctor, my cervix is looking beautiful. The downside of these cervix checks is that it means more vaginal ultrasounds. Just when I thought I was done.
  2. Fluid levels. Oooh fluids. Bane of my existence. My bladder was small to begin with.  Real small. Just ask anyone who has taken a class or sat through a movie with me. Now that I have babies pushing on it, it is a bit ridiculous. However, one of the main concerns with identical twins is that they keep even levels of fluid.  Twin to Twin Transfusion Syndrome is one of the risks involved with Mono/Di twins.  There is a whole bunch of scientific jargon behind this that you can read here, but basically you don’t want TTTS. It is unequal sharing of blood and fluids between the twins. One of the ways to tell if your twins have TTTS is the levels of fluid each twin has in their amniotic sac.  Equal levels are good. Equal bladder sizes are good. That is what my perinatologist is checking for. So far, we are great on this front. Equal fluid levels and both babies appear to have fully functioning bladders.  You go girls!

So, every two weeks I will be having a vaginal ultrasound and an abdominal.  It isn’t even that I mind that the vaginal is somewhat uncomfortable. I just am like… uuughh I am completely covered in ultrasound jam.. again.  Then again, it probably would be more uncomfortable with no ultrasound jam. However, I don’t really mind at all because it means I get to see the babies regularly and see that they are growing and fine and kicking each other…

16 weeks 2 2I like this one of Twin B because it looks like she is laying exactly how I like to lay. On my stomach with one leg up. Alas, my days of stomach sleeping have come to an end.

16 weeks 2Twin B has two legs. Two whole legs!

16 weeks Twin A is always harder to get pictures of because she is lower down.  If you are wondering how they come up with who is A and who is B, A is the baby closer to the exit.

    Your babies are beautiful! Can ‘baby a’ and ‘baby b’ change from one u/a to the next! Like if the babies flip? Or…

      I wondered that at first too. When they were really small it seemed like they moved all over the place, but now they are in the same position each week. So I’m guessing it’s not likely now that their space is getting limited.
