itchy?

my bfb (big fat belly) is so itchy right now - i have never had this with any other of my pregnancies. also, the back pain down my left side - whats up with that?? its amazing to see how different your nine months can go - we have 14 weeks to go now, which seems like a really long time, but im sure that it will just fly by and soon we will have another little babe in our house. maybe my body is just reacting differently this time because i have passed the big 3.0. hard to say. whatever it is, i will be glad when november comes so i dont have to keep scratching my bfb all day long.
