Cramps since 5dpo

Camille

So annoying, I have had cramps since 5dpo, I am now 8dpo with AF 7 days away. The cramps were centered in my lower right abdomin, and were quite consistent for 3 days. Then they went away or I just didn't notice them. Now.lying here in bed I have then again, almost throbbing with heartbeat. BFN this morning, although I know it's early. But honestly I don't suspect I am pregnant. Never had cramping with my first, and just wondering if I am pregnant, will it be a difficult pregnancy!? My first pregnancy was lovely, dreading having a difficult one....
