Birthing advice

I'm due to have my second child this month and I'm hoping to do a natural/no pain medication birth, if possible. I had the epidural with my first and had some complications when I was trying to push, hence the reason to go all natural this time around. I'm extremely nervous and having been reading about natural births and I don't feel prepared at all! I know the epidural is an option if I decide I can't handle it but I really want to try and do it natural but just feel overwhelmed when I think about it. Any advice?
