This week marks the halfway point for a normal pregnancy. For twins, it’s a little past halfway since most twin pregnancies give birth between 36 and 37 weeks. 20 weeks is traditionally the big appointment that most parents look forward to because it’s when they get to find out the sex of their baby; although this is starting to change with the recent development of the blood test for fetal sex.
We did not find out what sex our babies are because my husband wants to wait until the birth. I was super bummed about this at first, but now I’m excited for the surprise. I NEEDED to know the sex of our first baby but this time, we have baby equipment, it just might not be for the right gender. Regardless, there are certain blue things that we just won’t replace even if we wind up with two girls.
Everything went smoothly with the ultrasound (this was also the first visit we saw the OB who will be delivering them and who delivered our first son). Baby A (who is on the bottom) is measuring a few days behind my due date and Baby B (who is on top) is measuring a few days big. My OB asked about the possibility of two separate conception dates since they measured almost a week apart from each other, but I assured him that wasn’t the case.
I remember him telling me in my first pregnancy that the first trimester ultrasounds are the most accurate at fetal dating. When I had my first ultrasound this pregnancy, when we were still living in Boston, both twins were measuring exactly the same size. This means that since then, they have just had slightly different growth rates. He said that we will just keep an eye on the little guy and make sure that he doesn’t fall behind too much.
Baby A also had a brain cyst in one of the lobes which could point to one of the Trisomy disorders and we did not do any fetal or genetic testing so we don’t know our risk factors. It is most likely a variation of normal development because the baby has no other visible markers for the disorder and apparently those are normally very obvious. In a normal baby or one affected by Trisomy the cyst should dissolve on its own by 28 weeks gestation.
Once the ultrasound was over, I bombarded him with questions.
How long will he let me carry them before inducing me if I haven’t already gone into labor naturally? 38 weeks max was his answer. I was a little surprised since one of my friend’s doctors let her go all the way to 39 +5 but I knew that was super long. His reasoning was that the risk of one twin being stillborn spikes drastically after 37 weeks.
What happens if one of the twins is breech? He was totally ok with both babies being breech as long as they are frank breech with means butt first. That was shocking news to me and it must have showed because he proceeded to explain. He said that I’m a second time mom and he already knows my pelvis can accommodate a nine pound baby (Sterling was 8lb 14oz) and the twins will likely be under seven at their max. He said if need be, I should have no complications delivering a pair of breech twins vaginally.
He went on to explain that he would prefer me to get an epidural in the case that the he has to reach in and pull out or flip the second baby around. It is said to be a very painful procedure but one that I’m thankful he will preform if needed because it could drastically reduce the chances of me having to have an emergency C Section. Baby B can be very unpredictable and often will flip around once the first twin is out or floats up to the top of the uterus and only the bottom part contracts causing them to get trapped up high. He said, epidural or not, if he needs to reach an arm in and get the other twin, he’ll do it so I need to be prepared for that.
Decisions, decisions…. I’ll let you know what I decide!
