PS: I couldn't agree more with what's been said, you are most definitely NOT a failure! Sometimes things don't go the way we expect or hope but deciding to make changes to our original plans when those surprises come up is just being flexible and accepting of what's happening. In the end, the reward is the same. *hugs*
Good luck Heather! I hope things speed up now. I fully agree with PP's...you are not a failure for needing to consider some different options. You have been faced with some tough circumstances and a very long labour. ((Bighugs)). You've done great and if you meds an epi or other intervention to get through, just remember those do have their place and are needed at times.
