Usually two scans are done during the first trimester.
A dating and viability scan, between six and nine weeks and an early morphology scan or NT scan between 11 and 13 weeks.
Early pregnancy can be a very exciting time and often couples want to see their baby as soon as possible.
This scan is available to anyone who wants some reassurance, but particularly for those who are unsure of their dates, have had some bleeding, pelvic pains, concerns, or have felt that their early pregnancy symptoms have disappeared when they should be present.
Dating a pregnancy accurately at the earliest possible time is important.
In a normal pregnancy it does not matter what the dates are, but if anything should go wrong it becomes very important as to what treatments may be prescribed.
If your menstrual cycle is longer than 28 days it is advisable to wait until you are at least till 8 weeks from your LMP to confirm the viability of the embryo as you may not be as far as your dates suggest.
For instance a dating scan done at 6 weeks could get the date wrong five days either way.
A scan at 12 weeks could get the date wrong seven days either way and a scan done at 20 weeks could get the date wrong up to ten days either way.
You are required to have an adequately full bladder for your early pregnancy scan.
There is certainly no need to be uncomfortably full.
