So I'm 20 weeks pregnant, and I'm a bigger girl in the first place. When I look at myself in the mirror it makes me so self conscious. I feel so gross, and disgusting with my size that its ruining my sex drive.. I know I should be excited about my pregnancy, but i feel like you cant even tell I'm pregnant. I feel like I'm just gaining weight and that I've become unattractive.. how to I change my outlook on this?
