Yes - planned a waterbirth in the midwife unit of a hospital. I was going through transition by the time I got in the tub, pushed for 1 1/2 hours in the water and then my contractions started slowing down...I was really exhausted, practically dozing off between each contraction. So I got out of the water and onto the bed into a semi-sitting position and pushed for ANOTHER 1 1/2 hours before I finally pushed DS out. I honestly didn't think at that point that I would be able to birth him w/o some kind of intervention, thank goodness I had a birth team (DH, doula, nurse-midwife, nurse's assistant) who were DETERMINED that I would do this. I'm convinced that if I had gone with an OBGYN, they would have done an emergency c-section. Or at least used forceps.
chalk it up to waiting 36 hours in the hospital AFTER my water broke for labor to start, then 20 hours of labor and the effects of taking the sleeping medication they offered me the night b/4 to help me relax.
Not the worst hospital birth in the world...but I'm doing it at home next time!
