Hi and welcome!!
Cammie is beautiful and looks like a bulldog to me for sure. My 8 month male bully is slender and doesn't have that "bulldog" look you're describing - which usually means they are possibly overweight, which you definitely don't want. Also, females are typically smaller than males. Herman is developing slowly and just a few days ago he was less slender than he is now. Next week he'll be chunky again LOL Most of the healthy bulldogs I've seen are slender, muscular and have a nice shape - the ones that look like typical bulldogs seem to be overweight (even their owners will admit it).
What you want to look for is her being at a good weight - you can feel her ribs and spine (it will feel like there is a thin blanket between your fingers and the bone), and that she has a distinct waist when viewed from the top. Also, look at her from the side - her tummy should be higher than her chest.
Her body is going to change every day, and in about 3 years you'll know what she will really look like when she grows up
