don't feel pregnant anymore?

Im 21 weeks pregnant and ever since I knew I had a bad UTI when i was 19-20 weeks ive been worried about my baby. My UTI is gone now and dotcor says im fine but i just dont feel pregnant anymore. I don't think i feel him move yet and my stomach is still small and flabby. I Just feel fat. I wonder if hes still in my stomach. Im just worried.
