The main reason for the ultrasound is to work out how many weeks pregnant you are, and to estimate your due date.The length of your pregnancy is calculated from the first day of your last menstrual period (LMP), even though you don't actually conceive until 14 days after your LMP, and later than this if your cycle is longer than 28 days.If you type the dates in the pregnancy calendar on this site, you will see what I mean:-) Good luck!I guess my point was really that it is possible that it is your baby still given the dates, however there are other things impact these dates such as average cycle length, which is generally 28 days, but can be shorter or longer depending on the woman.
