Any other preggos have a hard time with putting on enough weight while pregnant? I'm 28 weeks-ish and have only put on 3 ounces. I swear I'm eating so much all the time, but it is just all going to baby. Any suggestions? (Also, sorry in advance, I know this isnt the typical problem. ONLY time in my life that I havent been able to pack on pounds by just LOOKING at food.)
