Is my baby OK?

So I took you with me on my 12 week scan and shared pictures of our little one still forming in the womb but I didn't get into the ins and outs of what happened that day. For those of you that don't know the process of testing an unborn baby for Down's Syndrome and other genetic problems has changed since I was last pregnant nearly 6 years ago. You now have the option of a nuchal translucency (NT) scan. During your scan they tell you they will measure the thickness of the back of the baby's neck, they are actually measuring the fluid underneath the skin, this can be used to determine the risk of that baby having Down's Syndrome.

During our scan the sonographer took what felt like an age to measure this and I was convinced there was something wrong. After the scan we received our results from the midwife and the measurement our baby had was 3.1mm. Apparently the cut off is 3.5mm.. so anything lower than that doesn't fall in to the risk category.

There is also a blood test which you can have (didn't feel like I had much of a choice).

The blood test measures:
• hCG (human chorionic gonadotrophin)
• PAPP-A (pregnancy associated plasma protein)
A woman who is carrying a baby with Down's syndrome will have abnormal levels of these two substances in her blood. You are given a result of 1 in ? and the cut off is 300. A woman with a 1/300 chance or higher would be classed as high risk. They told us if we fell in to the high risk category we would be contacted (by phone) within 7 days... if we were low risk we would receive notification (by post) within 2 weeks.

We received a letter yesterday (meaning we were low risk) and informing us that our number was 1 in 536.

It's all very well saying your "low risk" but surely there are degrees of low risk.. they don't tell you what "normal" is because everybody is different but if the NT scan cut off is 3.5mm and we're 3.1mm... wouldn't that worry you? What do other people get? 2mm? 1mm? And 1 in 536 chance of downs.. ok the cut off is 1 in 300 but some people get results of 1 in 1500.. when you put it in to that perspective.. 1 in 536 isn't exactly LOW risk, is it?

When I was having the scan and fearing the worst I thought the baby wasn't okay and I wasn't scared or upset I was practical. I knew we had a higher chance of conceiving again since Lee's test results had been so positive at the last fertility appointment and if this pregnancy wasn't meant to be it wasn't meant to be!

Since then I've thought a lot about it and and I just haven't become attached to this baby yet. I've tried but I'm not. I am excited when I think we're going to have a baby but it's a mixture of not really believing it yet and not wanting to be too disappointed if something does go wrong. So many people both in the public eye and that I know are losing baby's at 4 and 5 months + I feel like the baby isn't really mine until it's here and healthy. Hopefully I will feel more positive soon but right now I'm getting excited... but not TOO excited ... just in case.
