I feel the same way. My body has changed so much I've even developed stretchmarks. I'm happy about my pregnancy and can't wait for my baby to arrive . But the body change is so overwhelming it has put me off having another one.
No you are not the only one. Pregnancy is a beautiful thing because you end up with the best gift in life, a child but it is also a bit depressing not very many women love the changes in their body while pregnant. I am in my second pregnancy and as much as I love my babies it still makes me upset to see my self in the mirror.
