Weight on women?

Are you overweight and it's very humiliated to sit up straight or hard to bring back comfy at all? Im 199 and lone 26 and I am 5 "4 :(
I'm also 2 months pregnant but i was 194 previously I got pregnant i suppose or something like that I am considered obese. I don't hold a lot of trouble sitting up straight or getting comfy. Sometimes, if I've be on my feet adjectives day, my breasts get my back hurt, and that make it difficult to sit up straight.
Pregnancy can do that though. Between the bloating and the pressure, that's probably why.
