Speculate, would women's cycles be different on the moon than they are on the earth?

Menstruation is NOT dependent on the moon or any other planet or celestial object. Menstruation is based on the (usually) regular release of particular hormones from the hypothalamus and pituatary gland which direct the ovaries and uterus to prepare for the release of an egg and the ability of the uterus to allow the fertilized egg to attach to its wall.

There has been this centuries-old myth that menstrual cycles are related to the orbit of the moon around the earth. It is actually coincidental that the lunar orbit is approximately 28 days and most regular menstrual cycles repeat approximately every 28 to 30 days.

Therefore, assuming an atmosphere which would allow continued life for a woman, there is no reason to believe that her cycle would become radically different were she to live on another planet or to be in outer space.

It would be interesting to see. You know, we all seem to comment about how crazy things are when there is a full moon. Can you imagine how bad it would be to live on the moon during your menses???? Yikes..the men would want to go to another planet just to get away from us for a week...

No. I would think they would be the same - just like a man's cycle, but without the crossbar, wink, wink.
