Depends. The better ultrasound uses a wand, coated with gel and
inserted into your you know what.
There is a clearer picture or even video quality look at your
insides to know what is wrong.
So be prepared to take off pants. And dont douch before you
go.
If your appoint for the scan is in the afternoon, I would suggest
you bring a extra pair of panties, just wash up a bit before you
go, wear clean panties and change to a new pair after the
event.
