Im worried about my blood pressure?! Am I doomed for Preeclampsia?

Ive been taking my own blood pressure at home.(Yes, I know how.). Its been ranging anywhere from 140/50 to 190/100. Before I was pregnant, It was always 130/70. Im pretty concerned. Im going to talk to my Dr. about it tomorrow, Im just curious on your take on it? Im almost 22 weeks pregnant. I know about pregnancy induced high bloodpressure without preeclampsia...but am I doomed for preeclampsia? Im scared. Anyone have their own experiences?
