19 and expecting my first, questions about labor?

Let me start off by saying my baby boy was not planned. I was not on birth control, but our condom broke. I know that everything happens for a reason, so our baby was put into our lives for a reason. Either way, my boyfriend and I cannot wait to meet our beautiful baby boy. I'm about 25 weeks along, and have a wonderful support system.
I've taken parenting classes and have heard many horror stories about labor lol. 
To all the mommas out there, what was labor like? No need to sugar coat it, because i want to know your experiences. You can leave your stories in the comments below. Thanks!
