Girls, who had preeclampsia?

Girls, who had preeclampsia? Today I had an ultrasound, they said preeclampsia has the lowest threshold for normal values. Is this very bad? Who gave birth like that? On their own or with a cesarean section? Early or on time? My friend had preeclampsia, she was put on bed rest at 34 weeks, then had a planned C-section. Something I'm panicking about))
