The only reason you will have a third trimester ultrasound is if your doctor needs to get an ‘inside’ view of an ‘outside’ signal.  Some signals might be the amount of amniotic fluid, the position of the baby, low foetal movements, bleeding or lower back pain.  For me it was fundal size (the size of my belly).

I felt a little bigger than normal (I’ve already had three babies so I had a reference to go by) and when the doctor measured me I had jumped up the fundal percentage graph. It wasn’t anything to worry about but the great thing was my doctor believed that I could sense that there was something a little un-ordinarily about my size.  So he ordered another ultrasound.

As Moose is in Dublin (at a U2 concert – lucky duck!), I had to go to the ultrasound at the hospital with toddler-in-tow.  I wasn’t concerned, Norwegians are great with kids and they always accommodate them.  I was ready to practise my Norwegian but my ultrasound physician was a young man who was happy to talk English.

During the appointment I found out many things about my condition.  First off the sex of the baby was a definite.  The head was measured and it turned out that the baby is very big (- when we looked on the graph it was a little above the progressive lines – yikes) but the physician said that because of the way the baby was laying it sometimes distorts the calculation and therefore the measurement should be a little less.  The baby’s stomach is smaller in relation to the head but over the next couple of weeks the baby should fatten up.

The baby is laying in an awkward position.  This is what is making me bigger.  Its head is on the left side, the spine is up against my diaphragm and the legs are dangling to the right.  It certainly feels weird when the baby kicks as I get it from both sides of my belly.  As I’m in my final weeks the baby should turn (usually later as is the norm for subsequent pregnancies) but because it is so big it might get stuck.  I was instructed by the physician that when my waters break to lay on my back because the umbilical cord might come out with the waters when the baby is in such a position.  The cord coming out first can cause infection so laying on my back will help to prevent this.  If my waters break and the baby is still in this awkward position it is likely that I will need a c-section.

The physician measure my amniotic fluid in all four quarters on my tummy.  5-25cm2 is the norm – I am 22cm2 – so a little on the high side.  Hopefully this will give the baby enough lube to swivel round into a good engagement position.

Because there are so many ‘ifs’ I need to go back for another ultrasound in two weeks (if my body can hold out that long…lol).  I asked if I would need to be induced if the baby’s head gets too big – and yes, it is likely but it is also important to give the baby enough time to engage.

So, like always, it’s a ‘we’ll see what’s gonna happen’ scenario.  That’s the way pregnancy is – just like a box of chocolates.
