Ooh, shiny new 'fred, welcome to newbies Pinkandwhite and Hewhodares 
Hew; I'm 18+3 and haven't had tender boobs for quite a while now, but I do have new bras that fit better and I'm using an elasticky sports bra/top to sleep in, not sure if that's helped or if it just wore off. They've stopped growing for now!
2 weeks until my scan, can't wait! I've been watching OBEM and actually find it ok to watch, not quite sure how though.
