I was due for one when I was pregnant with my first - but my GP said I was fine to leave it until after baby was born if I was more comfortable with that. Apparently there is a very very marginal risk associated with it, which, because it was my first I wasn't willing to take (worried 1st time mum to be and all that). I just had it done at my 6 week check when dd was born. Mind you, after all the prodding around they do anyway, I probably wouldn't object if they advised me to have it done.
This time round there has been no mention of it at all, even though I know I'm due for it.
