Worried

Kia • Married 3 children one on the way
I'm 17 weeks and 2 day's this is my third pregnancy and I'm a little worried I don't any pregnancy symptoms whatsoever in the beginning I had nausea and fatigue but now I have absolutely nothing I'm thinking maybe I should call my doctor and schedule an early appointment but don't know if maybe I'm overreacting sometimes I feel like I feel movement but than I second guess it and not real sure anyone can give me insight ?going through the same thing or something
