I bought this belly band. Do you think it will help

Hi all, im only 5 weeks 2 days but I got in early and got two belly bands so when it comes to Christmas and I’m 10 or so weeks it will help me look a bit more pregnant in my Christmas dress! I’m telling my family on Christmas Day and I want to look my absolute best for family photos!

But not to mention my back is killing me and I’m hoping this band will help with support and rounding out my apron belly! So what do you think? Also do I wear this band over my jeans or under?
