Symptoms changing

I have been cramping, very mild, intermittent for the past week and a half. Got a positive digital 2 days before AF due, now I am on Day 2 of missed period but my cramping is lessening and not as often. The only other symptom I have is tender breasts. Should I be concerned that the cramping is lessening? As I've seen previous posts about cramping lasting for awhile. Thanks ladies!
