Pregnancy changes

I am starting to realize that I can’t really fit into any of my clothes anymore & it is bothering me to the point that I want to cry. Idk if i’m upset because i’m gaining weight or if i’m upset that i have to spend money on new clothes for the time being. As you are probably wondering this pregnancy was very unplanned and very unprepared for. I am also noticing that I am getting darker in some areas which is also bothering me. I am just so over whelmed and sad & honestly just want to cry.
