10 week dating scan
You won’t have known that you’re pregnant long, but your 12 week dating scan offers an exciting opportunity to see your little one developing in the womb and give you an idea of your estimated due date (EDD).You should have your first pregnancy ultrasound scan in between 10 weeks and 13 weeks pregnant, but it can vary on a couple of other factors including where you live and how you’ve been up to the 12th week of pregnancy.In around 3 to 5% of pregnancies, results are classified as higher risk, but most of those women will still go on to have healthy babies.It can be frustrating and worrying if you’re not given a definite answer, but it is important to have a fast and effective way of screening for potential problems with putting baby at any risk.Transabdominal ultrasound will provide a panoramic view of the abdomen and pelvis and is noninvasive, whereas transvaginal ultrasound provides a more limited pelvic view and requires insertion of a probe into the vagina.
Scans in early pregnancy are usually performed in the first trimester around 12 weeks.
The combined results of this test combined with a nuchal translucency scan will be used to calculate the chance of your baby developing Down’s Syndrome.
If you haven’t had the combined nuchal scan and blood testing for screening for chromosome abnormalities, you’ll be offered a screening blood test between 14 and 20 weeks.
• Check your baby’s general development including their heartbeat, limbs and some organs • Other potential abnormalities including spinal bifida • Most hospitals will be able to sell you a copy of your scan photo for a few pounds or ask for a donation Most units will offer you a screening test at the same time.
Screening tests for Down’s Syndrome is best performed after the dating scan as an accurate due date is required to assess whether hormone levels are actually abnormal or normal for that stage of pregnancy.
If there’s any cause for concern then you may be recommended to have the scan before the 12-week mark, and your midwife will be able to assist you with this.
