Have there been any big changes in your life recently, or maybe coming soon? Dreaming of being pregnant would seem to me to be about change or responsibility. How did you feel about being pregnant in the dream? If you were upset or afraid, especially with no father in the picture, maybe you are dealing with a burden and you feel like you have no one to depend on. If you were excited or happy, maybe you are feeling ready to take on something new that you haven't been ready to deal with before.
