Has anyone experienced diarrhoea type cramps?? I am 31 weeks tomorrow... throughout my pregnancy I've experienced period like cramps on and off. Since hitting 30 weeks I've been having what I can only describe as diarrhoea type cramps. I don't have diarrhoea but it's the same feeling as when you do have it and you need to go now. It's been happening 2-3 times per day. Has anyone had this?
