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.
Consider what things the Planets perform not by their Aspects, and observe if they do them not by their Antisions, for the Antisions have power, and are not to be enumerated amongst Aspects. - William Lilly (1602.-1681.)
