weird pregnancy dream

Cynthia
Every one in a while before I get my period I have this dream. I don't know why but last night I had a dream that I was pregnant and I was feeling the baby moving around. It felt so real, even more so that I have a son and I know the feeling. And I've been told by two people maybe I am pregnant because my son wants his dad more then me now and because he is acting out more then usual.. any one else have these dreams or heard about that wives tale?
