Hi i am 14 weeks pregnant nearly and am showing but im not sure what sorta clothes to get. Do you get a bra few sizes up or a proper maternity bra as mine are getting too small to wear. I have been buying like clothes which sizes are like 1 or 2 sizes up but how do you know how big your going to get. How do the maternity clothes sizes work-is it like 3-6 motnths or something like that? Any advice be much appreciated
