Stress/Pregnancy can definitely cause crazy dreams like that. Just trust your doctor and your baby is fine. :) I know it's hard to have that dream and calm yourself down afterward and I wish I could say it got easier, but eventually the dreams went away for me. That made it better.
On the plus side, i had a micro preemie 1lb 11oz at 25 weeks, they are so much stronger than you think.
Its probably from all the family drama ive had..thanks
I had miscarriage dreams in the beginning of my pregnancy too. It's scary, but it's just our nerves. Don't get too worked up over it that it causes you to be nervous all the time.
