I’ve been in early/latent labor since Tuesday have been having contractions on on and off all night however since 5am they’ve been more intense, actually woke me up, and coming every 5-6 ish minutes however I wouldn’t exactly describe them as super painful more just uncomfortable can still continue to do usual activities they’re just very noticeable. At what point should I ring the hospital. I live over an hour away and don’t want to go too soon but don’t want to risk leaving it too late. No sign of waters already being broke that I’m aware off.
