Anyone with a B-belly??

I was wondering. I am 20 weeks pregnant with my first today and have had a B-belly since forever. I am plus size and don’t show yet, but I am wondering whether I will only have a B-belly pregnancy? Or whether my B-belly will turn into a cute D-belly? I lost about 55lbs before falling pregnant and still had a B-belly, although much smaller.

I also want a cute D-belly, especially for the maternity shoot. Any tips or advice?

Here is a pic from Google for reference. It’s not me, though. Too shy to show my B-Belly here.
