I am 17 weeks and have been getting cramps quite low down in my abdomen. I saw the midwife yesterday and she suggested it could be an irritable uterus. She didn't really say much else. Having googled it, it seems to be more common later on in pregnancy (I found an old thread here from 2013).
Does anyone have any experience of this so early on? Did you have a premature labour or anything like that?
