Baby in wrong position for dating scan
If you're seeing a private obstetrician or an obstetrician in a public hospital, she may also do a short scan at some of your antenatal appointments.
These scans can be used to check the general health and growth of your baby and how your placenta is working.
If your doctor or midwife recommends a scan and you'd rather not have one, ask her to explain her reasons to you. You'll naturally be very worried if your scan suggests that there's a problem with your baby.
Sometimes a clear diagnosis can be made from the scan, such as spina bifida.
The sonographer will use a cover similar to a condom and will lubricate this with plenty of gel, so it slides in easily.
The vaginal transducer is long and narrow to fit comfortably inside your vagina.It's to check that your baby is developing normally.
