This scan will be your first glimpse at your developing baby and we can accurately give you your due date of your baby. Measurements are taken such that the dates of the pregnancy can be confirmed or determined. Other information obtained includes whether the pregnancy is in the uterus or outside the uterus an ectopic pregnancy , how many embryos there are, and whether there are any complications surrounding the pregnancy at this early stage. The ovaries and kidneys are also examined. When you arrive for your scan you will be asked to fill out a form about when your last menstrual cycle took place if known and some other details relevant to the scan. You will be asked to lie on the table and to expose your tummy and a towel will be tucked into your pants to limit spread of the gel onto your clothes. The gel that we use is water-soluble so it does not stain your clothes.
