My periods have changed completely in the last 6 years or so. When I was younger, they used to start very heavy, with excruciating back pain, and then ease off, last about 5 days altogether. Now (i'm 40), they are ridiculously heavy for two days, with lots of clotty bits, ugh, and continuous terrible stomach cramps (which I never ever experienced when I was younger), and it's all over in about 2 1/2 days. Then I usually get a bit of cramps and spotting about halfway through the cycle (whichis also annoyingly short now, 24 to 25 days!). Is this "normal"? Is there such a thing as normal?!
