I am so sorry you lost your precious baby! I lost my first one too, because I developed severe PE around 20 weeks and had to deliver at 26. Henry lived for one week.
Preeclampsia can last up until 6 weeks postpartum and/or only occur postpartum. The reason is that the process set in motion during pregnancy is not always stopped abruptly with the delivery of the placenta. For some of us it takes some time before your body recovers. With my second baby preeclampsia was worst the first two weeks postpartum. I had blurry vision, uncontrollable blood pressure and just felt awful, and was even readmitted to the hospital. Since you are 7 weeks postpartum, it probably is expected that you should have recovered. I would, however, always double check with your doctor, so they can keep an eye on you.
Welcome to the forums, but I am so sorry you had to find us. Please keep asking any questions you might have or let us know how you are doing, there are unfortunately too many of us who lost their babies. Sending you hugs.

Our pain has been put into words, placed into empty cradles, to remember that all our babies lived, that they mattered and always will. - Field of Cradles http://www.fieldofcradles.org/
