Natural birth question ?

I have 2  kids already a girl that's 2 and a boy that's 1 and I had a vaginal delivery with an epidural for both, they came out perfectly healthy . This is my 3rd pregnancy I'm 26weeks with another girl. This time around I want to try labor without any drugs no epidural, but I want to know is natural birth hard ? What can I do to prepare and ease the pains?
