How is the menstrual cycle affected by space travel?

Im seriously wondering how this would work...
Please give me your theories or studies or whatever information you have to cure my curiosity.

Menstruation is the result of hormone levels. It is affected in no way by space travel. Your hormone levels in space are exactly the same as hormone levels on earth. Even the expelling of menstruation is caused by uterine contractions, so I doubt lack of gravity would case menstrual blood to pool in the body. A tampon would probably solve this problem.

ie: it is not affected.

Not sure but the lack of gravity could cause an awful mess
