Thanks ladies,
I figured it was probably all pretty uncertain. I did mean to ask my ob specifically at my 6 week check but it slipped my mind. As I said, he smiled and said he would see me if I had another one... he knows I had a PPH so surely he would have suggesting no more if it was very risky? I guess sometimes just hearing people go on about what a hard time I have had starts to get to me. :shrug:
