Changing body

As I've started to begin to have a little bump I've had a hard time feeling good about how I physically look. I've always been lucky to be active and athlete and always had a tight little tummy( although have always had a booty and hips). As now my tummy has started to change and to me looks like I ate too much pizza, it's been difficult finding clothes where I feel comfortable with myself. My mom says this is just an adjustment and that once I have a true bump it'll be much easier... Thoughts to my other ladies out there??
