Morning sickness??

CJ

I am seven weeks and one day and have yet to have any morning sickness, only light nausea (yes I am grateful!). My sister in law said she didn’t have any when she was pregnant with her twin boys so she thinks I’m having a boy. However, my sister said she didn’t have any with her first one (a girl) but had it horribly with her two boys. I know everyone reacts differently to pregnancy, but I’m curious about everyone else’s experiences. Morning sickness or no? Boy or girl?
