My back and feet.... When did I get so huge?

Laura • 1st baby September 2015 🎉✨🍼
My feet have recently become increasingly swollen and painful and my back hurts terribly. I'm a full time nurse and I'm on my feet 12+ hours a day. I've tried new shoes, posture positioning, yoga, etc... I have no idea what else to do?! Also, I've gotten ENORMOUS in the last week. Started at 118lb and now 126. I can't even bend down without baby Dominic in the way!!!!
