What happens when you give birth?

I was never medicated during my last two deliveries. Labor began with menstrual like cramping with tightening of my belly. As time goes on, the cramping worsens and gets closer together. Them come the urge to push. This urge feels like you have to have a major bowel movement. You can not control the urge except with shallow breathing. When they allow you to push it will be relieving. After that it is all a blur to me. I had some pain but it seemed so exciting that I don't remember too much. Every labor and delivery is different. Go in knowing you will feel pain but it is temporary and you will have a beautiful baby when it is all done. Good luck!
