I'm at the end of my pregnancy and have begun analyzing every contraction I have. Is this one stronger than the last? Where in my body do I feel this the most? Is this painful or just uncomfortable? My gosh, I can't even gauge my own body anymore. And I don't know what I should be feeling because I've never gone through this before. To those how have gone into labor on their own, how did you "know" real labor was happening?
