When will I start to show

Okay so I keep getting asked when willy belly pop. I'm exactly 13 weeks and 2 days this is my first pregnancy and of course I started off a little over weight and I'm starting to think that I may never show and it's starting to upset me big time. Any advice or anyone know when I will pop?? I know everyone is different.
