Do ultrasounds hurt?

Don’t they have to stick something up your vagina when they do an ultrasound? I’ve never done one before. I can’t even use tampons because my vagina is too small to get one in there & tampons hurt me. & my husband’s penis will barely go in there too because my vagina is so small.? I’m so scared an ultrasound will hurt! :( ?
