Dreams in themselves don't carry a whole lot of significance; usually, they're just random images thrown up by the mind as it sorts through the data collected during the day. Recurring dreams tend to be associated with recurring thoughts. I would suggest that if you keep dreaming of having a baby, it's because you are consciously reminded of childbirth at some point during the day. Occasionally, dreams will manifest our desires and fears, which could mean that you want to have a baby on some level--but this is a dream that most of my female friends have had, especially during their ovulation period. It's normal and healthy to want to have a baby, provided you're responsible enough to raise one. I wouldn't attach any future significance to your dream; it doesn't mean you're pregnant, or that you necessarily will become pregnant.
