Boy or girl?

What are the tell tale signs that you mummies believe in to guess if it is a baby girl or boy? I am still active, no morn sickness. Still able to go to work and no picky for food. Some say by looking at my tummy, it's a girl. But some say it's a boy because I'm still strong hahahaha! Anyone can ease my mind? I got a feeling it is a boy though! ? Gender reveal is next wk so I really cannot wait. ?
