Hi, if I were to tear during a UC here I would either go to my OB/gyn or if she wasn't on call I would simply go to the ER. I had 4th degree and 3rd degree tears from the TWO episiotomies I was given at my last hospital birth. So I'll take extra care if I do tear at home that I am transported(with help of dh and whoever else is there to assist) with minimal movement on my part just to make sure I am as gentle as possible to myself:)
I haven't had personal experience with cord clamping but I read this thread recently and found it very informative: http://www.mothering.com/community/forum/thread/1306406/cutting-the-cord
Hope that helps :)
Oh and using the search near the top of this webpage to find thread's on any specific issue I might be wondering about usually brings tons of threads with lots of personal experience as well as links to more resources etc.
Congratulations and goodluck! Hope it turns out great for you one way or another :)
