Like "Yeah..I know what you mean..mine always start off light briefly, then, WHAM, they are usually moderate to heavy bleeding. However, mine never did last a whole 5-7 days . I bleed pretty heavy for 2 days, maybe 3 days, then it stops. I am very thankful mine only last 2-3 days. One day a few years ago I was at work and it started--OH, geez...embarassing--I lost so much blood my face turned sheet white--I got through it all, but just in general, it was also very very painful...ANNE"
