My pediatrician left a bruise

Ashley

So my newborn had his first check up. Hes 5 days old. Itty bitty thing only 6lbs and 8ozs! But of course he hated the doc like any baby does. Today I'm changing his diaper and notice a nice sized thumb print bruise. I'm kinda pissed cause I thought he was bring rough but to me everyone is too rough with newborns.

Here's a pic, does this look like. Bruise? Am i being paranoid? Should I say something to the office??
