Body changes suck!

First off, I would like to say this post isn’t for sympathy, I just need to vent to some ladies who will understand. Me and my hubby are expecting baby #1 and we’re SO excited! However, recently I’ve been struggling with how my body is changing. I was never small, but I’ve always been healthy and in shape, played sports all through high school and college and I’m a fitness professional. But now I’m dealing with new stretch marks in places I didn’t even know I could get them and I’m in that awkward “is she fat or pregnant” stage. I know I’m growing a tiny miracle, but this is also hard for me mentally. Hubby is as understanding and supportive as he can be, but won’t really understand completely because, well, he doesn’t have to go through it. Anyone else dealing with this type of issue?
