Hi and welcome to the forums!
Here are some general odds for the risk of getting pre-e again: http://www.preeclampsia.org/forum/viewt ... f=19&t=331
If preeclampsia does strike again, it tends to be less severe or later in gestation.
And please don't let my sig scare you, I probably have higher than normal odds since my dad and husband were both pre-e babies. Many of our members have gone on to have healthy second pregnancies.
I hope this helps, good luck!
