Girls, hi everyone) Share your story — how did you realize you were in labor? I've been suffering from false contractions for over a month, I've already been in the hospital, and I'm always afraid I'll miss the real ones because of the false alarms. I'm curious how it was for you: what did it feel like, how did you know it was THE real thing? ???
