I remember having this fear! Its normal to worry. The only thing I can say is stay away from the loss stories if you can help it. If your having dreams about it, its only your subconcious dealing with your fears, and is in no way a sign that its going to happen.

If your antenatal carer is monitoring your high blood pressure, and informing you of pre-eclampsia, then I think you are in pretty safe hands. Maybe get yourself informed a bit more on pre-eclampsia and what to look for, that way you can feel more at ease that you know what to look for if you need to.
Maybe keep a daily note of movements if it will make you feel more at ease. I remember when I felt my DD kick Id take note of the time so that if I did need to remember her last movements, I would.

I know its hard, but relax a little bit, and if you have any concerns at all, dont brush them off, get them checked out.
