Anxious……..

I’m at 16 weeks but to be honest it worries me because at this point, the morning sickness/symptoms have mostly reduced and…1) I don’t feel much, 2) I don’t feel baby kicking and 3) my baby bump is…..very little (almost none, not sure if I’m imagining it at this point). I will only have my next appt at the 20th week so tbh, I’m not sure what to do with this newfound anxiety in this 4-week wait……. (Not to mention additional family things causing me extra stress/concerns….) Anyone has advice….?
