Fat rolls to baby bump

Hello ladies. I was just curious when you went from having fat rolls to having a rounded bump (if you did). I am 19+2 and definitely have a bump, but there is still a crease and rolls. I think it's kind of starting to round out but not quite yet. Was wondering when it rounded out for you?? My crease is where I tie my scrubs so I feel like that contributes a little but I want there to be no doubt in a stranger's mind that I'm pregnant and not (just) fat lol.
