Over the past 3-4 months I've adopted a vegetarian diet (although I still include seafood, eggs and cheese). Since then I've noticed a dramatic difference in my periods.

Previously, I experienced heavy and long flow duration (about 8 days with the heaviest days being the first 4) and extremely bad cramps (typically only the first two days, without Midol or something in large doses, i wouldn't be able to function).

Now, my period is almost the opposite of what it was before the diet change. I experience a very light start (only needing a pantyliner or two a day, for the first 2 days), then I have a normal flow for about 2 days, and I have almost no cramping.

I'm not complaining, its been a great change. I just want to know if my assumption that the vegetarian diet is what is helping, or if my symptoms might be caused by something else that I should get checked out for?
