Natural birth?

Catherine • Expecting a baby girl on September 25th, 2016💘💘 || Toronto, Canada
I am 17, going to be 18 when the baby is born. I am planning on having a birth without an epidural as I have minor spinabifida. Any advice ladies? How was it? Was the pain manageable? 😩 I'm due in September and the closer I get, the more nervous I get.
