Well... just to keep you all informed.
It has stopped for the time being. And bubby is ok, and my tummy measured fine at my appointment.
I talked to lisa, she said that if it's stopped its probably not anything to worry about, but if and when it happens again to get it checked out. She said it's probably just an alarming increase in cm/preg discharge and hence it now seems to be 'normal'.

Thanks for all your concern and assistance. Shall be sure to update if anything further occurs.
