It is believed that pregnancy in a dream often reflects new idea or events coming to fruition; bodies of water, ponds and lakes, are said to represent your emotions and your unconscious and sometimes romantic feelings too.
So I guess, going by the above, that the dream was about letting go and allowing yourself to accept whatever emotions may occur and whatever new ideas or schemes you have going in your life at the moment will not cause you any deep hurt emotionally.
Also dreams can be very cliche-ridden sometimes, I guess there might be something big about to happen that you are excited/worried about, because of the countdown to the jump, and your fears are that there's no going back if you don't 'bail out' in time. I guess that the lady who doesn't land in the pond is the more cautious side who frowns on adventure and risk-taking, but your unconscious mind is trying to suggest to you that she is probably wrong this time - or that you should go for it regardless just for the fun of it?
