Iirc, this is actually true. There has been some studies that suggest that the moon phase does influence menstrual cycles. I don’t fully remember what the researchers concluded, but I remember vaguely that it was something like, not seeing the moon (if the sky is overcast, for instance) doesn’t affect the menstrual cycle, but looking at the moon will “reset” the cycle in some way.

OP’s friend might’ve read something based on it too
