Hi, I'm 6 weeks gone (first pregnancy) and have had cramping for the last 48 hours. It's woken me up the last 2 nights and woken the BF also due to moaning in my sleep. During the day it's been more like a bad period but at night it is really quite painful. I fully expected to bleed but there's been no spotting. Is this normal? I read that you're supposed to call Doc if cramps are 'severe' - what constitutes 'severe'?? Anyone got any advice / reassurance? :)
