Getting sooooo impatient!

I want to feel baby already and see my belling growing! I’m 18+1 and barely have a bump. I see so many plus size ftm here and their bumps are so round and big at just 15+ weeks. Every morning I lay on my back for 20min hoping to feel flutters and nothing. Once I go to the bathroom I’m hoping to turn in the light and finally see my belly has “popped”. I know these things are dependant on the person, but I can’t help but to worry if baby is growing properly.
