Bump ambivalence

Caitlin • First baby! Stepma to 👯
12 weeks in and the only "bump" I have just looks like I had a big lunch. It makes me anxious to actually start showing and excited to get a big, powerful bump. 
On the other hand, it's pretty scary to think of not being able to suck in when I DO have a big lunch!  Well aware this is a vain concern and completely out of my control, but am I alone here? Or maybe these conflicting feelings are just preparation for the roller coaster of parenting?
