Feeling Huge & Miserable

Sa

25 weeks and I’m feeling so big in the middle and pains everywhere. Feels like I’m overstuffed especially when sitting down all the time. My hips and back are so sore. Feeling like I don’t know how I can survive until the end! I am not overweight now or before pregnancy. I think my body isn’t used to carrying extra weight? Anyone else feeling awful as you get bigger? Tips on ways to alleviate would be appreciated. Thanks!
