Hello. Just finishing off my birth plan. Am hoping for as natural birth as possible if things go to plan but am still undecided about delivering the placenta naturally. 
My thinking is, if I manage to get through it without an epidural I've done bloody well enough and maybe I'll just want to get it over and done with and have the injection, but on the other hand, if I manage as naturally as possible, surely I should try and do the last stretch?!
I would really like to delay the cord clamping, but is this possible if I have the injection for the placenta? Lastly, how much longer is it likely to be to deliver the placenta naturally: are we talking minutes?
Sorry for the long winded post: basically please tell me everything you can about getting placentas out!
