29 Weeks and still dont feel the baby move alot....

So just had an appointment yesterday and doctor says everything is good we hears her heart beat was a good 143. I forgot to ask when I was there as I had an hour appointment an pretty much asked everything else. I just turned 29 weeks today measuring 31 and I am a bigger women 240 before getting pregnant and I still don't feel any strong kicks more like just flutters an rolls. hard to explain but I was wondering if this was normal or do u think my baby might still be small?
