I'm 36w3d and I'm having pretty regular Braxton Hicks contractions right now. I've been having them pretty consistenly for the last hour. They aren't painful just uncomfortable. I've been drinking plenty of water and I'm not staying in the same position. I'm getting some back pain with them but it's not really painful just annoying. I feel like I'm WAY over thinking it but what did early labor feel like for you? When did you call your doctor? How did you "know" it was labor?
