I vomited during transition.
I actually have a funny vomiting during labor story, believe it or not. At about 2 AM, after 12 hours of labor at home, I decided that it was time to meet our midwife and doula at the hospital. Because the hospital is only a few blocks from our house, we decided to walk. Along the way, I started throwing up from the pain. A police car pulled to a stop next to us, obviously expecting to see some drunken college students heading home from a frat party. When he saw that it was actually an extremely pregnant, obviously laboring woman headed in the general direction of the hospital, he took off like the Devil himself was chasing him.
