There is a lot of information out there about the chances of recurrence - my advice would be to meet with a specialist to see what your chances are. I was told by my perinatologist that usually, if you get PE again, it is less severe and occurs later in the pregnancy. In my case, I ended up with just high blood pressure. My labs were trending towards PE levels, but I went into labor prematurely, so it didn't have a chance to progress.
There are so many unanswered questions after experiencing a loss like this, but you can be sure that getting PE wasn't your fault. That was the first thing my peri told me - there wasn't anything I could have done to prevent it. I guess that's one of the most frustrating things about PE - we have absolutely no control over it.
The first few months are the hardest, but it will get better with time.
