Anyone found exercise affecting thier periods?

Just that really...

Ive been reading abit about it after being nearly 2 weeks late myself and wondered if anyone had any personal experience?

I had a partically hard week just before I was just due on (kickboxing grading) and am wondering if this could be a cause.

yes... not a problem for me, and not sure I was ever going to be super regular anyway.

When I was younger & fitter my periods were only every two months or so. I used to do weights, aerobics, waterski & swim & had very low body fat. Periods were still heavy, just infrequent.
