for the last couple of hours I've been having quite regular contractions ( every 20-30 minutes) my stomach tightens up for about 30 seconds and a couple have been uncomfortable verging on a little painful. I'm 39 weeks and I've been having noticeable braxton hicks for about 6 weeks but they have been getting increasingly strong and uncomfortable but never this regular. I haven't had any other signs ( show/ waters breaking although I've had increased discharge) do you think these are real? They don't seem painful enough to be the real thing!
