Getting crazy....think that baby has disappeared

I do not know maybe I’m getting paranoid, but I constantly think that pregnancy is gone. I had last scan at week 12 and everything was fine, NIPT came back good, sex confirmed. I’m 17 weeks tomorrow and next scan is on Thursday, but I do not feel pregnant!!! I do not have belly, just fat layer that I grew and bloat in the evening. All nausea is gone, sometimes short breath but that could be from being less active, tired in the evening. I do not feel baby moves and belly is not even hard or round like everyone is showing on pictures. I’m so worried, had 2 miscarriages before but at early in pregnancy and I’m 39, this is my first baby. Am I completely crazy??? Is anyone without belly and baby moves?
