Hi OP
I opted for a home birth with my first because my mum had had two HBs and my sister had two straight forward births so I felt quite confident it'd be OK.
I read several books about natural birth; Birth Skills by Juju Sundin, Natural Childbirth by Ina May Gaskin, and something by Dick Grantley-Read.
These three books were all a bit hippyish but I took something positive from each of them - one had loads and loads of natural child birth stories which really helped to read, and Juju Sundin had lots of coping mechanisms for getting through the "waves" (contractions).
All in all, these three books plus a CD of Marie Mongan's hypnobirthing really really shaped my positive experience.
Birth - contractions started Friday eve, baby born Sat around midnight, so about 30 hrs.
I was examined on Sat eve around 8pm and MW said I shouldn't expect anything before the morning as I was a first time mum.
Pain was pretty low level here, minor niggly back ache and period cramps.
I was wearing a tens all Saturday.
At around 10.30pm things were getting harder and my waters had broken, so we called MW and asked her to come back. She didn't believe us but reluctantly said she'd come back.
At half 11 she still wasn't here (lived 10 mins away!) and I could literally feel my baby's head in my vagina! so we called back and said get here now!
She arrived at five past midnight and DD was born at 0016!
It was textbook and super manageable. I only had two paracetamol at about 8pm and my tens. In fact the tens was so effective I could only cope with it turned about half way up, and higher and it was worse than the contractions.
I had my second baby at home too, straight forward birth but complications with placenta (due to miscarriages between the two babies).
I can't tell you just 'not to worry' but knowledge is power, knowing what will happen to your body, what needs to happen etc really helped me.
I used breathing exercises and loud counting from my DH whilst pacing on the spot. (Visualisation helped me too, I imagined I was cycling up a hill and every step I took was another pedal. There's a big hill near my so I know it well and used familiar points to get me up the hill.)
Good luck OP. Fingers crossed for you.
