Does anyone know what the chance of preeclampsia repeating in a second pregnancy? I was diagnosed at 28 weeks?

with my son and he was born at 33 weeks after 5 weeks of bedrest. I am currently 7 weeks pregnant with #2 and wonder if my chances are great again. I am only 23 and do not have any other risk factors. (I am of a normal weight and do not smoke.) My doctor is doing tests, just wondering if anyone here had any experiences with this.
