Full Bladder for First Appointment

Kristin • Married 8/16/14💍 Pierce Jaxon: 6/5/16💙👶🏼 Logan Marie: 2/27/18 🎀👶🏼.

I totally forget from my first baby but for the first prenatal appointment is there anything specifically I need to do? The receptionist didn't say but I feel like I am supposed to have a full bladder for the transvaginal ultrasound... is that right? Anything else!?
