I found out on Thursday that I'm pg (been trying). Today I put a bra on and I'm toppling out of it - told dh who laughed and thought I was being silly as it's far to early... he then stopped speaking, looked at me and said: "Oh my, you're right... they're huge!" Cue big smile from dh.
4 weeks is still early isn't it? At this rate I'll be in maternity clothes by 8 weeks!
