pregnancy rut

I am sosososo thankful to be carrying a healthy baby and no complications thus far. I'm 30 weeks and just feel very blahhhh. Though I've put on close to 30lbs I still fit a lot of my leggings etc (for now) but am starting to bust out of everything-I know tone expected. I'm a SAHM. I do pretty good about keeping house clean and cooking but I just feel so blah. My husband calls me beautiful but I do not feel it. I'm always wearing my "house clothes" big tshirt and yoga pants. Hair on top of my head and no makeup.
