This isn't about UC or natural childbirth. It's about hemorrhage. I'm not "on" the UC board, but your post came up in the new post list and I really felt the need to correct your egregious misinformation.
I'm going to bow out now, so as to not further derail the OP's post.
So long. Too bad your only argument was that you are a doctor. If you actually had something to teach us, you totally missed the chance.
