Self-conscious while pregnant..?

So I took pictures today with my husband on my cute Christmas shirt that says "Bumps First Christmas" with a ball ornament with baby feet on the tummy and I started to look at them to post them to social media and noticed my face getting rounder..the shirt also wasn't a tight fit shirt, so my while body just looks bigger...I'm starting to get a little self-conscious about it...my doctor told me to be careful about weight gain at my last appointment because I've gained 13lbs so far and that was when I was 21 weeks (I'm 24 weeks now). I guess I'm just feeling kinda ugly...I always thought that problem would get a little better when pregnant because I'd love my body changing with the baby in me, but when it comes to my face getting bigger like it is, I'm not too thrilled..

Anybody else with the same issues? How did you keep from your face gaining so much weight? The rest is mainly just my baby belly, unless it's mild swelling of my feet and hands..I'm could just use a little encouragement..
