Tired of nightmares

Mercy • I'm 27 years old and me and my husband are expecting our 2nd baby in March. Our daughter is almost 2 and we are excited to be giving her a sibling!
I keep having nightmares and in them I keep having miscarriages and it's really getting annoying! When I went to the doctor last week everything was fine and the baby looked healthy. This is my 1st pregnancy and I'll be 9 weeks tomorrow and with how sick I've been feeling I know this baby's strong. I guess It's just nerves but I'm  definitely ready to get off of the 1st trimester roller coaster. Anyone one else have these bad dreams?
