If you’re a man and you dream your ex-girlfriend is pregnant, the dream imagery can not be taken at face value. You need to conduct your own checks to confirm the validity of this dream. Dream interpretations can yield different meanings for this dream.
In dream symbols, imagery of an ex-girlfriend can mean an old hobby/ project which you had spent considerable time on in the past. If you think this dream imagery might refer to your old pursuit, then the dreamed pregnancy may refer to a hint that it is time to relook into the old project/ hobby. The dream imagery of pregnancy can mean the “labor of love” could be ready to bear fruit.
