I don't have any pics but I didn't really have much of a bump until 30wks, then it just appeared from nowhere!
I sometimes look at it now (1 day off 40wks) and think it's huge, but then I see other ppl who are 25+ weeks with much bigger bumps and think it's small.
I haven't had any strangers ask me about bump so I guess I must just look fat!! lol.
I am not wearing maternity clothes either, just normal clothes, one size bigger than my usual size.
