What can i expect for my first vaginal ultrasound? what will they do? is it more uncomfortable or painful? how can i relax

Not painful.: It should not hurt, unless there is a painful problem already. The most discomfort comes from having the full bladder necessary for the procedure. The device is a little larger than a tampon, and feels the same. Just as when inserting a tampon, relaxing the vaginal muscles makes it painless.
