I'm 38+2 and for the last couple of nights I've been getting painful cramps and then an urge to go to the toilet. It only seems to happen when I'm in bed which I find strange. Last night I woke up in the middle of the night with them and I generally thought I was in labour but they went in the end. Anyone else experience this? Do you know what this could be? Does it sound like Braxton Hicks or the start of labour?
