How accurate is an ultrasound if you do not remember your period?
If you do not remember the date of your last period you can have an ultrasound to determine your due date. More than one ultrasound throughout your pregnancy may be required because ultrasounds are not always accurate. They could be out as little as a couple of days by a matter of weeks.
Do they back date ultrasounds to the 1st day of your last period or your conception date?
Most doctors revert back to the first day of your last period.
Will doctors be able to tell you when you got pregnant if you are in your second trimester?
If you can remember the date of your last period they should be able to work out your due date and from that they can work out when you conceived. However, if you can't remember the date of your last period, ultrasounds and measuring the size of your bump can be used to work out how far along you are, so you can work out roughly when you got pregnant
How far along you are you?
On average you can work this out as the number of weeks from the beginning of your last period. If you don't know or can't remember or your periods are irregular an ultrasound is quite accurate.

ultrasound is more accurate. Measurments of the fetus are made during ultasound that give a more accurate gestational age
How does an ultrasound detect when your last period was?
An ultrasound does not detect when your last period was. An ultrasound measures the size of your baby compared with the millions of others that have been scanned and gives an estimated date of delivery. Up to about 20 weeks of pregnancy all babies are about the same size. After that the size of the baby depends more and more on genetics and nutrition. Counting back 40 weeks from the estimated date of delivery gives an indication of when the last period might have been.
