I might call the nurse line, but I'm sure they'd tell me to head to L&D for a check. Around this point last time, they just always told me to go to L&D whenever I called!
I'd go and see your medical professional - I am 30wks today and have had the same thing - I am told I am in labour but very slow restricted to bed rest and if my waters go or the pains get worse or more frequent to go back to the hospital - at the end of the day what are you willing to risk?
