Heavy uterus

I'm 16+4 and I think baby is hanging out on my left side. It feels so heavy and I feel movements on that side. My right side feels completely normal. I read about an old wives tale that said If baby hangs out on left side it's a girl and right side it's a boy. 
I've been having dreams of it being a girl so we will see :D find out on April 7th!!!! 
Anyone else have this weird feeling??
