Im a cancer also, which is probably why I automatically go to the moon LOL. Although last night I had to pull my curtain across a bit, its was too bright LOL.
To be perfectly honest I have never really put that much thought into it. But really it makes sence. The moon not only rules the cancer sign, but fertility & all things womenly. So to me, I think during AF, we are open more so. But instead of realising its a chance to absorb, we tend to let it escape KWIM? Most women often feel drained & crappy around AF, but I wonder if we just focused that "draining" energy the other way, we could use it to our advantage.
