When will it end? !

When did you guys notice that the cramping (uterus stretching) stopped? I will be finished with my first trimester tomorrow, and I haven't had much cramping, but it's been through out my months. Maybe one cramp every 3 days or so. But I'm wondering will it stop and come back once you get close to the babies eviction notice or continue through out the whole pregnancy. Do you guys still have cramps? Even after so many months?
