I was so worried with both of my pregnancies that I wouldn't know when I was going into real labor, even with the second one..and I knew what real labor felt like from the first. I read that if they go away when you change positions, then it is not real labor. Start timing the pains. If you notice you are getting them at regular intervals that are increasing.. every 10 minutes then every 5 minutes.. and changing position doesn't make them go away a little, I'd call the hospital to talk to a nurse to get advice. When they are 3 minutes apart and really strong, I'd go in.
