Dating scans, which are often performed around the seventh week of pregnancy, were one of those interventions she said needed questioning. As soon as a pregnancy test returns a positive result, most women are able to work out when their baby is due using one of the numerous due date calculators on the internet or with the help of their GP. Dating can be done at the nuchal translucency scan which can detect chromosomal abnormalities at about the twelfth week of pregnancy. The other is an anatomy scan, where a lot of important developmental problems can be picked up, around 20 weeks. While a pregnant woman might be eager to see that flickering heartbeat and reassure herself all was well with her bub-to-be, Ms Eddy said they should instead be guided by the usual early pregnancy symptoms such as nausea, fatigue and having tender breasts. Rachael McEwing, a radiologist who is on the Maternity Ultrasound Advisory Group, said because unnecessary dating scans were being carried out, some women who really needed scans may not be able to get an appointment. Ministry of Health statistics show a trend for pregnant women to have more ultrasound scans over the past five years.

Like many young couples starting out, we were full of hope for the future. Hope that one day we would have a family with two, maybe even three, children. Like many couples we also waited until the time was right to start our family. Sick of all the questions of when we were going to have children and all the over-analysing looks whenever I chose to drink coke instead of wine, we finally decided the time was right.
We had been married three years and my husband left halfway through a three-year tertiary course to go back to work so that I could stop work to look after a baby. We were pleasantly surprised when I fell pregnant after only one month of trying. Being a teacher, the timing was great as I could finish out the year with the baby born close to the Christmas holidays. I knew the first 12 weeks were crucial but remained quietly confident because miscarriage happens to other people, not me.
Desperately I wanted to see my baby on the week scan but had decided not to go for the pre-screening tests. My husband and I are practising Christians and had decided that we would love any child. I said those words to my midwife so flippantly that I never knew the next few months would test those words and our faith to the core. My midwife recommended a dating scan.
