You need to call the doctor about this. It could be nothing or something very serious. I'm a good example of that.
I had that with my first and it was because he actaully bruised me from the inside out (he was 40 wks exactly). He also bruised my ribs.
With my second (born 3 days before EDD) I had it again and this time the doctors thought it could be my placenta detching so we did a 1 hour ultrasound (very boring baby slept the entire time lol) and they gave me the option of induction that day or wait 2 days and do the US again. I choose induction (better safe than sorry ya know) but as soon as they hooked me up to the monitor I was already having contractios 10 mins apart, just not noticing them lol. So my placenta wasnt detaching BUT they told me it looked like there was something wrong with it (long story).
