A pregnant belly in a dream, regardless of your actual circumstances, usually symbolizes new potential taking shape -- an idea, project, or version of yourself still growing beneath the surface. The anticipation in the dream often mirrors real excitement or nervousness about what's about to become visible.
There will neither good or evil be performed, but when the good or bad planets in a nativity or revolution shall aspect the Moon by a quadrate. - William Lilly (1602.-1681.)
