Here I am 38 years old and done having kids. I had a son when I was 26 and another son when I was 35. When my periods started when I was almost 15 years old they lasted a full week. Day one was weak, day two and three were moderate and days four through 7 were light with the last day being just spotting. Some months I had KILLER cramps. Then, I had my son. still had a similar pattern, but now they were 4-5 days long with day two being significantly heavier. ALSO I had very few cramps and not severe. Then... I had my last son. Now my periods are never longer than 4 days and on day 2 I feel like the Super Plus size tampon is tiny! The flow is SOOOO heavy. But, is this because of having kids? or just age? My Mom had four c-sections and she said she had the same thing, so it can't be because of my cervix being more "open"... Why do you think that is?
