Nightmares

My SO and I have been ttc for just over a month, and more recently I've been having these really vivid dreams about being pregnant, giving birth, and babies in general. Not just any babies though, these are mine. Recently my SO has been having terrible nightmares about me having severe health problems due to being pregnant. He dreams that I'm given a 50/50 shot of both me and the baby surviving, and that he pleads with me to terminate the baby.

If someone could give me some advice on how to make them stop, share stories of their own baby nightmares, or if they could interpret the dreams, I would really appreciate it.
