Quoting Heather Maples:" I have had my bloody show, lost my mucus plug and ive leaked colostrum. Also have had some sharp pains ... [snip!] ... some sharp pains n pressures, how and when did u know u were in labor. My doctor n hospital are a hour away. When do I go in?"
Oh! And I would go when contractions are 7 min apart. If you labor like me the car progresses labor like fast just the bumps and jiggles so it's a good idea to be a bit earlier when you're that far away. I personally would never make it to the hospital if I lived an hour away. I live 5 mins away and barely make it in time.
