I'm 15wks pregnant as of tomorrow, i'm not particularly showing. Or rather it depends on the time of day. In the morning im not showing and still slim. But as the day goes on my belly seems to grow

/ Is this normal? I'm not feeling pregnant, i'm just feeling fat.
I keep thinking that I am feeling the baby, but probably not as it's not 'fluttering'. It kinda feels like a push, but I can only feel it on my hands, not on my belly...
Only 3wks til my scan, I can't wait to see bub again. I hope by then I look pregnant and can feel something.
