I've gained about 20lbs so far, at 28wks. To be honest, I really don't give a crap how much I gain this pregnancy, LoL! I am probably a little more relaxed because with all my babies, breastfeeding has done WONDERS for taking the weight off FAST. But the biggest difference this pregnancy is that after our son died last year, little things like weight gain are at the bottom of my list of concerns.
I know it can be sucky to gain more weight than you wanted to. I know it can be super sucky to outgrow your MATERNITY clothes, lol! But as long as you and baby are safe and sound, try to enjoy it! Enjoy your pregnancy, the miracles your body is performing underneath your skin, and the precious baby who won't care WHAT you look like when s/he is born! Your pregnancy is such a short, short time in your life. In the grand scheme of things, even if you gained 100lbs this pregnancy, these 9 months don't have to ruin your body for life.
