Ladies with Anterior placenta... Is this the baby moving?

Toni • Our Rainbow is due 1-9-16 🌈
Hi mamas! So I was told at my ultrasound that I have an anterior placenta and that would mean it might take longer for me to feel the baby move. However, I'm definetly feeling something that is not gas. It almost feels like out of nowhere I can feel a pulse down there. I wonder if maybe that is the baby? Or maybe I'm actually feeling blood flow in my placenta? I'm 16+2, and have felt this a few times. Any experience with anything like this?
