Having a scan in the first few months of pregnancy can be a thrilling experience.
It's amazing to see the little blob with a heartbeat that will soon become your baby.
We ask that you to fill your bladder by drinking a pint of water before the scan.
This makes it easier to see the uterus and ovaries as the full bladder pushes away the overlying bowel area.
You may have calculated the length of your pregnancy from the first day of your last menstrual period (LMP).
This is even though you don't actually conceive until 14 days after your LMP, or later than this if your cycle is longer than 28 days.
Generally, ultrasounds which are performed in the first trimester are within 3-5 days of being accurate in terms of assessing gestational age.Crown/rump length and gestational age are closely compared with each other until around the end of the first trimester.The ideal time for a sonographer to assess the gestational age in the first trimester is between 7-10 weeks of pregnancy.At around seven weeks of pregnancy, it’s reasonably common for women to have their first ultrasound.This can be for many reasons but the most common is to confirm pregnancy and to check that the embryo is viable and “everything’s ok”.
