Birthing classes?!

Chelsea • Married in May 2011. I have two babies, both born on Valentine's Day 2012 and 2016. 💜💚
With my son I missed our birthing class by one day, he was early, and because of this I opted for the epidural. I didn't think I could handle the pain by myself or even push properly for that matter! 
My question is, should I take child birthing classes this time or am I just freaking myself out?
