Measurements were spot on. Just for the record:
Head Circumference: 117mm (15w4d)
Biparietal Diameter: 30.6mm (15w3d)
Femur Length: 17.7mm (15w1d)
LO has grown so much in the past three weeks - we could see his/her profile, arms and hands waving around, long skinny legs stretching out and lots of wriggling going on! We managed to get a lovely profile shot so we could see LO's little nose, lips and chin.
Mr Beattie sat in on the scan and confirmed that the kidneys, bladder and brain are still looking totally normal. To that end, he confirmed that LO does NOT have Meckel-Gruber Syndrome!
I can't begin to express what a relief that is for us - it means we can continue to hope for LO's future. And it also means that Charlie's chances of cuddling his living, breathing sibling have increased greatly.
Heart-wise, everything is still looking wonderfully normal so far.
We had another good look at the four chambers, and were also able to visualise the pulmonary artery and aorta.
So everything still appears very normal for this stage of pregnancy.
However, it's still only early days in terms of cardiac scanning, so the doctors are unable to completely rule anything in or out as yet.
However, each time they scan me, they are looking very hard for any abnormalities, and the fact that they have yet to spot any can only be interpreted as very good news.
So we are happy and greatly relieved with LO's progress so far.
The sonographer did try to find out whether LO is a he or a she, but those long skinny legs were firmly jammed together, so we'll have to be patient for a while longer!
We go back on May 10 - a couple of days after we get back from Crete - for the major anomaly scan, at which point I'll be 19w2d and almost half way through my pregnancy.
We should be able to get an even clearer picture of what's what by then, and should be able to rule out a lot of potential problems, as well as have a better look at the heart.
A few weeks after that, we'll be seeing Orhan Uzun, the fetal cardiologist, for an in-depth cardiac scan, at which we should be given some concrete answers.
I will be glad to finally know what's happening - I am not really allowing myself to get excited or start daydreaming, because it's just too hard to have it snatched away if a problem shows up.
For me, pessimism and realism are the order of the day until I have absolute confirmation that I can stand on the rooftops, singing!
The only other interesting thing from today, is that Mr Beattie has asked me to speak at another symposium, again about antenatal diagnosis, on May 11. I can use an amended version of the talk I gave last time, so it won't be too much work.
And it will be the day after the anomaly scan, so maybe, just maybe, I can edit in a happy ending!
You are doing so well, LO. Keep up the good work!
