I've literally convinced myself my baby's dead

I am so sick to my stomach. I have this bad feeling that my baby died. I made a post earlier about my belly looking smaller. 
Today after I took off my bra my boobs seem smaller. They were getting huge and now they look small , like there's a huge difference. 
I almost don't even feel pregnant anymore at all 
And I don't know what to do. Hospitals won't do anything that I know of unless your bleeding  and cramping. I had a miscarriage in October and I feel like I'm going to relive it all over again. 
Has anyone had sudden change in symptoms ? Breasts and belly looking smaller ? I'm 14 weeks. I can't understand why everything would look smaller now. My boobs were swollen for the entire stent of my pregnancy 
Needing some advice please 💜
