Accuracy of early pregnancy dating scans
And I don’t say that simply out of some concern for women’s self-esteem (although of course that’s important).
I say it because I know that there are things we can know from women and their knowledge of their bodies that no machine will ever be able to tell us, and we need women to understand that this important kind of knowledge is valuable so that we don’t lose our connection with it.
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.
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.
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).
We suggest that you go about your normal daily routine but just not empty the bladder half an hour before the scan.
There is a small chance that a transvaginal scan may need to be performed in order to get a clearer view.
(The authors go on to suggest that the best time to perform a scan to date pregnancy if one is needed is 11-14 weeks, although the rationale for this isn’t well explained).
But of just as much concern for me is the move that has occured over the past few decades whereby technologically-derived knowledge has become seen as superior to women’s own knowledge, which also includes the knowledge that birth attendants can gain from women’s experience of being in their bodies.
Early pregnancy can be a very exciting time and often couples want to see their baby as soon as possible.
