I am not planning on having a home birth but i have a question that I do no mean in any controversial way. aka…i'm not trying to stir the pot I am truly curious. What happens if there are complications? Do you call 911 and go to the hospital?
Often if there are complications or the Midwife feels one will arise (prolonged labour, early indications of possible fetal distress) they transfer to a hospital. The most common reason to transfer to a hospital from a planned home birth is for pain relief.
If you're really interested in this go and read up. Because home births usually have a set criteria ie. can't be high risk, have complications, etc and limited or no interventions (no pitocin, cervadil, epidural, etc) the rate of complications is much lower than the incidence of complications in hospital births.
You can read a study comparing birth/labour complications between low-risk hospital births and planned home births here. and an article about the study here.
