Haven't felt baby kicks yet

Ashley • I`m an Air Force wife currently living in Arizona, but will always be a California girl at heart. Pregnant with baby #1
Ok so I'm 19wks today and a FTM. I know they say it usually takes longer to feel if it's your first, but I'm getting worried I haven't felt anything not even little flutters yet. I'm also not showing and haven't gained any weight, dr doesn't seem concerned as I'm already overweight but I keep wondering when I will look and actually feel baby.
