So I never seen this has this happen to anyone? but since becoming pregnant and gaining weight my shoulders appear to be broader and my back is so wide and I have no neck now. I’ve become so self conscious about it and hope it disappears after giving birth. My pre weight was 121 and I’m 5 months now and 133.4 height 5’3 so not a lot but I guess that’s just how my body gains sadly. Even my husband notice and called it out. I honestly wished I would’ve gotten wider hips and not a big wide back on a small frame 😩
