I never realized what people meant when they said things like "oh trust me, you'll KNOW when you're having real contractions" until I went through both Braxton-Hicks and then later, the real thing. There is definitely a difference! My Braxton-Hicks felt really tight, hard, and were uncomfortable and went away when I would either rehydrate or change positions (sitting down to laying down or vice versa). My real contractions were, let's just say, incredibly stronger and no amount of movement would have made them 'go away'.
