Is this because of preeclampsia?

OB said I might have preeclampsia at my appointment last week. I just recently had something really stressful happen after and I’ve been crying a lot and now my ankles are like extremely swollen, I mean you can’t even see my ankle. I just got done crying & I look down bc my legs & feet are bothering me & they’re hugeeee. does that have something to do with the preeclampsia?
