FTM worries

I am about 16 and a half weeks pregnant for the first time. I have had some issues during this pregnancy. I am a relatively small person (5ft2, 110 lbs) and before the issues, I worked out regularly. I don't have an appointment until the 18th, which seems far away, because so far, I haven't really gained any weight or felt the baby move. I mean in the morning, I have a slight bump which seems to grow a little over the course of the day, but nothing like some of the pics I've seen on here. And no movement at all yet. Is it too early to be worried about all this or could it be okay? I have had 6 ultrasounds and heard the heartbeat at the past four appointments but I am still nervous. I just don't know what's considered "normal." Thanks ladies.
