pain after ultrasound

With my first pregnancy I had to have 2early/internal scans and didn’t suffer at all following them but this time round I have had to have 3 internal scans and each time afterwards I have experienced horrific stomach pains, more than period pain level but not quite actual full labour level just a medium. Anyone else had this issue? Baby is doing very well at the moment and no signs of anything negative shown on scan but I just cannot shift these pains
