Are ultrasounds meant to hurt?

I had my 13 week NT scan last fri and she was pressing around my belly button area and it HURT! I told her it was painful and she told me she just needed to get one more picture... and today when my midwife felt my tummy in the same spot it hurt again... it's really tender in the muscles around my belly button. Is this normal? Thanks!
