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.
They can guess by looking at an ultrasound. Your period is a good indicator as well. But it's all guess work really. But they're usually pretty good at it.
Both. If your periods are regular every 28 days your due date is pretty close to 40 weeks after your last one. However if your periods are irregular and/or you can't remember the ultrasound is accurate to witin 2 or 3 days up until about 8 weeks after conception as embryos all grow at the same rate.
After about 16 weeks it gets less accurate as some grow faster than others.
Ultrasounds and calculations from last period are a matter of statistics NOT guesswork
As long as you are very early in pregnancy, a doctor can usually tell you from looking at an ultrasound. There is very little variability in size very early on. It is later in pregnancy when individual differences arise.

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.
A prostate ultrasound is a diagnostic test used to detect potential problems with a man's prostate.
I think you are going to have to go with the ultrasound on this one.

the earliest this can detect pregnancy is 5 weeks after last menstrual cycle so yes the tech. may be abl;e to see the embryo.
The answer to both questions is no. The GYN can't tell, and ultrasound can only see changes if you're pregnant now or were pregnant in the last couple of weeks, at the most.
sonar is used to detect big penises
