Hi all
Glad to hear you're getting some relief from the sickness.
Amerikiwi - in the UK we get 2 scans, one at 10-14 weeks, which they badge as a dating scan, basically just to check that all is well with the little one and give you a more accurate due date (as some have mentioned, going from LMP and ov gives different dates, this is meant to clear it up). The second is at about 20 weeks, which I think is to check the development of the baby and, unless the hospital has a policy of not doing, they can also tell you the sex of the baby, if you want to know and it's laying the right way around.
I know they do a blood test (optional) for downs if you want it. Reading the booklet, they will also use the scan as a nuchal test, although it does say it needs to be done at 11-13 weeks, and my scan has been scheduled (by them, knowing my dates) for 10w 3d so I guess we'll see whether they even can do it or not.
Daisy - hope your scan goes well on Friday, will be thinking of you x
