Ok so I'm 25 weeks on Thursday and things have been sailing super smoothly! Loving every moment of it. Yesterday I flew from home in Philadelphia to Colorado Springs. I understand there's less oxygen here, I've been here before (not preggo) I've been huffing and puffing the entire time and my legs and feet just blew up! Swollen twice their size. Prior to this they've been fine and I work as a nanny of 4 on my feet all day long and this has never happened.
