normal for 16 weeks? first time mom here

Lexie
I've been seeing so many posts about women feeling their babies move around this time and I haven't felt anything yet. No flutters, nothing. I'm only 16 weeks, maybe it's too early? I'm just always worried that maybe there's something wrong with the baby (I haven't had any symptoms of miscarriage). I don't have a very noticeable belly yet either so it's just driving me nuts. My last appointment was right before thanksgiving and baby had a strong heartbeat and everything was fine. I don't have my next appointment until the 21 of December after I have my anatomy scan... the wait is killing me! I'm just scared that since I haven't felt the baby move yet that when I go to my appointment they'll give me bad news ): I don't know what to do
