I didn't have any symptoms. my feet and stuff was swollen almost my whole pregnancy but I didn't get preeclampsia until the last week of my pregnancy. my doctor checked my blood pressure like 10 times in 30 min and it kept getting higher so they had to induce me. I felt fine, just hungry so she let me go eat before I went up to labor and delivery.

Swelling, protein in urine, headache that won't go away with Tylenol, vision problems, but the biggest indicator is high blood pressure. I had it with my first pregnancy:/
