Chrissy Teigen is pregnant with her second child and she recently traveled on a plane and shared the troubles a pregnant women experiences when being in such high altitudes. Throughout her flight she tweeted out her experiences while flying. One of those tweets said the following: "My nose and gums are bleeding and my skin runneth over my compression socks." Although Teigen has said how far along she is or when her due date is, some have estimated for her to be four or five months. Pregnant women can typically travel by air until the eight month.
