Any ideas how to get labor going? I've been nauseas the past day and a half, lost my mucous plug for 3 days, and I've had diarhea for over 2 weeks. I'm dilated to a 1, and my contractions are getting more frequent and painful but always go away. I keep getting every sign that it's close but nothing yet. My doctor would like me to try to get labor started naturally so I don't have to be induced. Whats worked for you guys or people you know? Thanks in advance.
