Flutters

I'm 28+1 and for the past week or so I've been feeling only flutters very low in my pelvis, no more kicks up in my belly anymore. Is that normal? I figured that as long as I'm feeling something that I shouldn't worry but I'm still not sure. I saw her three days ago on an ultrasound that was done to get her heartbeat recorded for a stuffed animal for my grandmother and nothing was said about anything being wrong but I'm still a bit paranoid.
