More nervous about the second baby/delivery?

Ebev
Hi there!
I have a beautiful son who is 18 months, that I am so in love with. His labor was not easy, in fact it was the hardest thing I have ever done. He was also not so easy as a baby, either. Maybe colic? I guess? I Am less than a week from my due date, and I hate to say it but I feel so much more nervous about this, the second time around! Anyone else in the same boat? Everyone keeps saying "you've got this because you have done this before!"
