Since things can go wrong, I agree with some other posters, to have the birth in the hospital...but you can specify you don't want drugs unless you ask for it. Both my girls came early by 7 weeks and I didn't have any drugs at all. The pain for the 2nd one was starting to get a little bad and I asked for the shot but as soon as I sat up, the baby starting coming, so I didn't get it. So I had a natural birth twice but in the hospital. At one point with my 2nd one, they couldn't hear her heartbeat and had to reposition me, therefore I'm glad I was in the hospital. I don't know if its because my babies were small but the pain was tolerable and I've had worse headaches and stomach aches lol. I'm not sure what's the definition of a "natural birth" - to me its birth with no meds and a "home birth" is no meds and no doctors.
